After a helmet, a pair of the best mountain bike knee pads is probably the wisest protection to use. That’s because your knees are generally one of the first – and most painful – parts of the body to hit the ground in a crash.
As a moving part, your knees are also vital to protect, and wearing pads is one of the best ways to keep you on your bike, rather than resting on the couch.
We've taken the knee pads – or knee guards – in this list on both short enduro spins and longer cross-country rides to find out which pads go unnoticed on longer rides, and which get the sweatiest.
While protection is vital, if pads don’t feel good you’re less likely to wear them, so comfort has taken equal precedence in our reviews.
We have also included our MTB knee pad buyer’s guide at the bottom of the page to show you what to look for in your next pair of pads.
Best knee pads for mountain biking 2024 as reviewed by our expert testers
Sweet Protection knee pads
- Price: £90 / $100 / €100 as tested
- Protection: SAS-TEC knee cup
- Sizes: XS, S, M, L, XL
- Colour: Black
- Pros: Great fit; comfy for big days in the saddle; stable pad design
- Cons: Hard to knock
The Sweet Protection knee pads have quickly become our favourite pads out on the trails, thanks to their great comfort, secure fit and coverage.
The pads sat just right on our tester's legs. The stretchy sleeve has thick neoprene panels that help the pads hold their shape, even with bent knees.
At the bottom and top is a fabric with a rubbery backing. Paired with a single Velcro strap up top, the pads stay resolutely in place.
There is a thin stretchy panel and perforated fabric behind the knee to stop things from getting too sweaty. The pads warm up quickly but they do dry pretty fast, so wearing them for a multi-day trip shouldn't be an issue.
For protection, the pads use SAS-TEC knee cups, which harden on impact, a bit like D3O. While there might not be enough protection for downhill riding, these are some of the best trail pads available.
Fox Launch Elite Knee Pads
- Price: £144.99 / $165 / €155 / AU$250 as tested
- Protection: D3O
- Sizes: XS, S, M, L, XL, XXL
- Colour: Black
- Pros: Impressive comfort; well-formed protection; premium feel
- Cons: Pricey
The Launch Elite Knee Pads offer high levels of protection in a lightweight, tech-packed construction.
Large D3O cups span from the thigh to the shin offering plenty of coverage, with the malleable pads offering an EN1621-1 protection rating and remaining comfortable all day long.
The sleeve construction means there are no hook-and-loop straps, making the Launch Elites some of the comfiest knee pads we've ever tried.
Despite their high price tag, the fit, comfort and protection offered by the Launch Elites make them some of the best on the market.
7iDP Project knee pads
- Price: £110 / $120 / AU$220 as tested
- Protection: Extra protection around the outside of the knee
- Sizes: S, M, L, XL
- Colour: Black
- Pros: Impressive build quality; high levels of comfort; well-shaped
- Cons: Pricey; not as malleable in cold weather
While expensive, the 7iDP Project knee pads are feature-packed, justifying the price.
The pad itself, which is protected by an exterior skid plate, is extensively shaped around the knee, so feels odd when you’re putting it on, but great once there. It encases the sides of your knee, so while these pads don’t have the most protection real-estate on test, the padding is exactly where it needs to be.
The sleeve is made from a compressive knit material that’s exceptionally comfortable on all-day rides, and a rear cut-out boosts comfort further.
These are rock-solid in use, with upper and lower silicone strips, and a unique double Velcro strap system. We’ve found the core material stiffens in the cold, softening once some body warmth gets in. For pads with plenty of front protection, a bit extra at the sides wouldn’t go amiss.
Bluegrass Aura Knee Pads
- Price: £80 / €80 as tested
- Protection: SAS-TEC TripleFlex
- Sizes: XS, S, M, L, XL
- Colour: Black
- Pros: Great levels of articulation; decent protection; premium feeling; stay put when pedalling
- Cons: Pad needs to warm up for maximum comfort
The Aura Knee Pads offer an EN1621-1 level two protection level thanks to its TripleFlex cups that span from the thigh to the shins.
We found the pad gives good levels of articulation, but on colder mornings they were a little stiff causing small irritation until our body heat had warmed them.
The Aura Knee Pads inherit the premium feel of Bluegrass's top-of-the-range options making them incredibly comfortable on long days in the saddle.
Endura MT500 D3O Ghost Knee Pads
- Price: £90 / $120 / €100 as tested
- Protection: D3O EN1612-1
- Sizes: S/M, M/L, L/XL
- Colour: Black
- Pros: Impressive comfort; stable pad placement; lightweight and unrestrictive
- Cons: Sizing not the most exhaustive; a little rough on the inside
The MT500 D3O Ghost Knee Pads offer excellent stability thanks to their sleeve design which uses silicone gripers on elasticated hems.
Their hexagonal design provides great movement making the Ghost's comfortable on long days in the saddle.
The open ripstop front panel also provides good cooling on warm days.
We did find the sizing to be a little restrictive and the inside is a little rough.
Endura MT500 Hard Shell
- Price: £80 / $115 as tested
- Protection: Plastic shells and D3O insert
- Sizes: S/M, M/L, L/XL
- Colour: Black
- Pros: Great protection; plenty of coverage; good adjustability
- Cons: A little warmer than some
While they might not be the lightest pads, there's no getting away from how protective and comfortable the Endura MT500 Hard Shell knee pads are.
The pads use a combination of D3O inserts behind hard plastic shells. This padding is attached to a sleeve that extends above the knee for plenty of coverage. There is also some PU foam padding to protect the side of the knee.
To stay in place, the pads have silicone grippers and broad Velcro straps at the top of the sleeves. There is a second strap around the top of your calf muscle, which enables you to tailor the fit of the pads further. We found this means the pads didn't slip down or bunch behind your knee and remained comfy even on long rides.
The pads do get a bit warm, but that's no surprise given the protection on offer.
Fox Enduro D3O
- Price: £75 / $85 / AU$140 / €85 as tested
- Protection: D3O insert
- Sizes: S, M, L, XL
- Colour: Black, Grey Vintage
- Pros: Lightweight and comfortable; little interference; well-priced
- Cons: Not as protective as other 'enduro' pads
Despite the ‘Enduro’ tag, we feel these are slightly more trail-bike orientated because with a relatively simple D3O pad, they don’t offer as much protection as some other knee pads. However, they’ve won favour with a number of our testers thanks to their exceptional comfort and relatively keen pricing.
While the pad isn’t the most pre-shaped, the sleeve onto which it’s built hugs your leg closely, pulling the pad in and keeping it securely in place. With a snug fit and minimal rubbing, we’ve been happy keeping these on during all-day epics.
To help keep the air flowing, the rear section of the pad is perforated. The sock extends high up the thigh, where a silicone gripper holds it in place. At the bottom, the elasticated hem is tight enough to boost security without causing discomfort.
The pad itself is fairly long, extending low enough to stop most debris flipped up by the front tyre from leaving a mark on your shin.
The Enduros are lightweight, knee-warmer-style pads, so we wouldn’t take them on the chunkiest of enduro rides, but for riders looking for all-day comfort with plenty of protection and ventilation, these come out top dog.
Pearl Izumi Summit Knee Guards
- Price: £77 / $85 / €85 / AU$115 as tested
- Protection: D3O EN1612-1
- Sizes: XS, S, M, L, XL
- Colour: Black
- Pros: Comfortable and stable design; very unrestrictive; lightweight with good protection
- Cons: More side protection would be an improvement
The Pearl Izumi Summit Knee Guards are made from a four-way stretch Cordura fabric that allows for an unrestricted pedal stroke that keeps you comfortable for long days in the saddle.
We found the protection to be ample, with the D3O pad offering good coverage of the lower thigh to the upper shin area, though some may want more side protection.
The sleeve design makes for a comfortable and secure fit, with silicone beading used to keep the hems in place.
Rapha Trail
- Price: £80 / $110 / AU$140 / €95 as tested
- Protection: RHEON Labs CE level 2
- Sizes: XS, S, M, L, XL
- Colour: Black
- Pros: Extremely comfortable; high levels of protection; unrestrictive
- Cons: Not the most breathable
Rapha has hit the ground running with its debut knee pads. These are extremely comfortable and have good coverage and protection.
The feel of the material is similar to a set of knee warmers in that they are made from a very soft and stretchy fabric. There's a silicone print on the inside too, to ensure they stay in place, which we can attest they do.
The padding is made in collaboration with RHEON Labs from an 'active polymer' and is soft and malleable but hardens on impact.
The knee pads didn't disappoint when pedalling, despite having a reassuring bulk and they fit well under most mountain biking shorts. We'd be happy to pedal in these all day and they would stay perfectly in place while giving you peace of mind.
The knee pads aren't as breathable as some other options on the market, but for the comfort and coverage they provide, it's a small penalty.
Troy Lee Designs Raid
- Price: £110 / $115 / AU$220 as tested
- Protection: D3O CE1621-1 Level 2
- Sizes: S, M, L, XL, XXL
- Colour: Black
- Pros: Secure feeling; plenty of pad coverage; adjustable fit
- Cons: Not the lightest
The Troy Lee Designs Raid pads are some of the most protective pads here. Substantial D3O padding covers a large part of the knee area and extends reassuringly far down the shin.
Foam pads add protection along both sides of the knee, as well as just above the kneecap, making them feel very safe on dicey terrain.
Despite this, the fit is extremely comfortable, whether standing up straight or pedalling for long rides, and this feedback is echoed by several testers.
They stay up exceptionally well thanks to a pre-curved knee cup and a strap that sits above (not below) the thickest part of the calf. The Velcro strap above the knee allows the tightness to be tailored to the rider and stops it from moving around.
They’re not light, and they’re a bit warm, but given the level of protection on offer, we think this is easy to forgive. They’re comfortable enough for long rides and protective enough for gnarly bike park laps on the black run.
If you’re after big-terrain security without the comfort penalty, they have the versatility to justify the price tag.
Bliss ARG Minimalist
- Price: £70 / AU$90 as tested
- Protection: Super Shock Absorbing ARG
- Sizes: XS, S, M, L, XL
- Colour: Black/Blue
- Pros: Comfortable on long rides; plenty of cooling; stable pad design
- Cons: Fit is on the large side, so size down
The ARG Minimalists feature some of the longest pads we've seen. With the top of the sleeve extending well under some liner shorts, these stay in place nicely and feel unrestrictive.
The thin, stretchy sleeve is topped and bottomed by elasticated hems with a dotted silicone strip. It has a thin, leg-warmer-style construction, with a slightly more perforated material behind the knee, which we didn’t find bunched during riding.
The big blue pad is pre-formed to fit the shape of the knee, and while there’s plenty of space inside, we didn’t find it flared out or lacked security. We’ve witnessed some big crashes with these pads, where they’ve done their job well.
The Lycra sleeve means the fit is snug, but it extends a long way down the leg, so we needed to pull the pads up high to prevent the lower hem from being loose around the calf.
Fox Enduro Pro D3O
- Price: £95 as tested
- Protection: D3O foam
- Sizes: XS, S, M, L, XL, XXL
- Colour: Black
- Pros: Incredibly comfortable; pads stay in place well; plenty of coverage
- Cons: Need to be warmed up on cold days for the best comfort
The Fox Enduro Pro D3O pads offer great comfort once on, with the D3O insert wrapping well around the knee, though we found they needed warming up on cooler days.
A slip-on design is used for the Lycra sleeve, with an even tension pulling the insert close to the knee, making for a slim silhouette that should fit beneath most riding pants.
Silicone embroidered onto the sleeve on the openings keeps the pads from falling down.
While the CE Level-1 rated protection doesn't give the same peace of mind as burlier pads, they remained comfortable for long days in the saddle.
G-Form Pro Rugged
- Price: £100 / $80 as tested
- Protection: Impact-absorbing SmartFlex pads
- Sizes: XS, S, M, L, XL, XXL
- Colour: Black
- Pros: Soft fabric aids a comfortable fit; secure and stable pad position; good comfort
- Cons: Can get warm
G-Form’s pads use a D3O-like material that hardens on impact to offer plenty of protection, along with comfort-giving flexibility.
The pads' contoured shape shows through the hardwearing outer material, while the inner sleeve is medium-thickness Lycra, which is very soft against the skin.
For lighter-weight pads, the Pro Ruggeds wrap fairly far around the knee, as well as higher and lower than some. They stay in place well, with silicone dimpling around the lower hem and a strip up top too, backed by a Velcro strap. This attaches at the rear of the leg, which isn’t as intuitive as securing at the front.
The thicker material at the front of the sleeve adds warmth over similar-looking pads, but it’s not hot enough to cause issues on longer rides.
While pricey, the quality makes them feel worth it.
iXS Carve Evo+
- Price: £90 / $115 / €100 as tested
- Protection: Xmatter protection foam
- Sizes: XS, S, M, L, XL, XXL
- Colour: Camel, Grey
- Pros: Plenty of padding; good adjustment; comfortable for short sessions
- Cons: Bunching around the knee; bulky
These are some of the bulkiest pads we've tested, with plenty of protection and a secure fit making them feel very safe. The flip side is that there’s noticeable bunching behind the knee.
You can remove the pad itself for washing, and it’s shaped nicely to fit the knee and flexible enough to prevent any digging in. There’s extra padding above and to the side too. The iXS pads are held securely in place by straps at the top and bottom, which have plenty of adjustment.
While the sleeve isn’t the tallest, a thin silicone strip holds it in place. It’s largely made from a thick yet stretchy material that’s warm, but there’s perforated fabric at the back for ventilation. These pads are hot, but that’s acceptable given the protection offered, even if it does make them best suited to shorter sessions.
Leatt AirFlex Ultralite Knee Guard
- Price: £80
- Protection: AirFlex impact gel protection
- Sizes: S, M, L, XL, XXL
- Colour: Black
- Pros: Good airflow, comfortable on longer rides; no bunching around knees
- Cons: Not as secure as others
These pads are unmatched for trail-riding comfort, with the thin mesh sleeve having enough compression to prevent slippage, while not being so tight that the seams dig into your skin.
There’s more mesh fabric covering the AirFlex padding, giving them top marks for breathability, though we found the lightweight mesh material didn't hold the pads quite as securely as some others.
Effective bands of silicone grip help keep them in place, and there’s no bunching behind the knee. Coverage is decent, too, given their weight and size.
Leatt 3DF 6.0
- Price: £87 / $100 / €100 / AU$154 as tested
- Protection: 3DF
- Sizes: S, M, L, XL
- Colour: Fuel/Black, White/Black, Black
- Pros: Well-placed padding; bulky but comfortable; feels good against the skin
- Cons: Can get warm
The 3DF pads surprised us because, despite their bulky protection, they remained comfortable on all but the longest of rides (where a sleeve-style lighter pad always wins out).
A one-piece main pad is backed up by a pair of harder, yet still flexible, outer skid panels, as well as impact-foam side protection that extends up to the lower thigh. The sleeve extends fairly far up the leg and has both a silicone strip and a Velcro strap to keep it in place. Lower down, there’s a simple elasticated hem to hold things up.
The interior material feels good against the skin, and the medium-sized cutaway at the back means there’s no bunching and minimal flaring to contend with.
They’re fairly big, so are warm, but we found they worked better for longer rides than some more protective pads.
Pearl Izumi Elevate
- Price: £120 / $125 / AU$230 as tested
- Protection: D3O viscoelastic LP1 pads
- Sizes: XS, S, M, L, XL
- Colour: Black
- Pros: Unrestrictive; plenty of padding; impressive breathability
- Cons: Seam can irritate if pad is worn too low
The Pearl Izumi Elevate Knee Guards combine fairly high levels of protection with a lightweight-feeling design that’s very comfy in use, but at a high price.
The D3O pad is quite long, and extends far around the knee, with the outermost section backed up by further high-density foam on top. It’s visible through the mesh front, and ventilation is as good as you’d expect from looking at it. This is enhanced by mesh fabric at the rear and a large cut-out behind the knee.
The rest of the sleeve is very light, and extends high up and low down the leg, with a silicone gripper for security. There’s a touch of excess material at the top of the knee, and you need to pull them up high to get the best fit.
Our only real complaint, price aside, is that the open sleeve through which the D3O insert can be removed can catch on your feet as you put the pads on.
POC Joint VPD System
- Price: £140 / $150 / €160 / AU$225 as tested
- Protection: POC VPD insert
- Sizes: S, M, L
- Colour: Black
- Pros: Comfy to pedal in; secure feeling from protection
- Cons: Not the biggest protective area; pricey; only three sizes
Although pricey, POC's Joint VPD System knee pads proved incredibly comfortable and offer a good level of protection.
The pads rely on POC's VPD (visco-elastic polymer dough) insert. This is designed to remain flexible when in use but hardens on impact. There are three different layers of the material, which POC says not only helps absorb any energy in an impact, but also makes them highly breathable.
They're not the longest knee pads going in terms of coverage but they fit well and come in at a decent weight, too, at 372g.
They remained comfortable on long rides and you can pedal comfortably, almost forgetting you're wearing them.
SQUIRREL_13078774
Troy Lee Designs Stage
- Price: £90 / $89 / AU$158 / €90 as tested
- Protection: D3O
- Sizes: XS / S, M / L, XL / XXL
- Colour: Black
- Pros: Comfortable and breathable; good articulation; bulk-free design
- Cons: Not as much protection as other
Troy Lee Designs' Stage knee guards performed well and are a comfortable and highly breathable option.
They articulate particularly well when pedalling and fit well underneath trousers or shorts.
You can feel the edge of the D3O insert on your shin when your leg is fully extended, though, but we only really noticed it on longer rides. The coverage is decent but they don't have quite the same levels of protection as other options, as they only have a CE Level 1 rating.
We also found they've held up well after two years of riding, proving a durable option.
As well as not providing the same levels of protection, there are only three sizes, which we'd recommend trying before you buy.

MTB knee pad buyer’s guide
Velcro straps
Being able to tighten things down with a Velcro strap adds security, but also weight, warmth and inconvenience. If you want the best protection, though, Velcro-secured pads are likely a good option.
Fit is vital. A baggy, loose feel may aid comfort, but it can lead to the pad moving in a crash, decreasing the protection it offers. Some designs rely on a long upper sock with a silicone gripper to keep them in place.
Behind the knee
The area behind the knee is often where pads cause the most skin irritation. Thinner, more breathable materials tend to bunch and chafe less. Some pads have a cut-out here, which may add cost but can definitely help with comfort.
Articulated or not?
Your knees bend thousands of times during a ride and your pads need to be able to move with them. Soft pads articulate easily, but harder designs may have cut-outs to help them flex as you pedal.
Side protection
While the front-of-knee protection is most obvious, some designs have extra padding on the sides. This can really help when you bang your knee on the top tube!
Shin protection
Pads extend differing lengths down your shin – the deeper they go, the more protection they offer, but they'll also add more warmth and potentially more discomfort, if the pad itself isn’t particularly flexible.
Knee cup
This makes up the bulk of the pad’s protection and can be made from soft, foam-like materials, impact-hardening ones (such as D3O) or hard plastics. The protection is usually encased within the pad’s fabric and can be removable for washing
Ventilation
The trade-off for more security and protection tends to be less comfort and breathability. Unless you want to whip off your shoes at the top and bottom of every climb, your pads are likely to stay on throughout your ride. As such, you need a pair that doesn’t chafe on long climbs or get too sweaty when the sun comes out.
More protection
Knee pads are seen by many as necessary protection for tackling enduro and downhill trails, but if you're in the market for more protection, we also have lists bringing together the best mountain bike helmets and the best MTB elbow pads.
