Osprey Raptor 10 hydration pack

Feature-filled pack for all day riding

BikeRadar score4/5

The Raptor 10 is just large enough to carry everything you need for extended backcountry riding while leaving the kitchen sink at home. As the name implies, the Raptor 10 has 10 liters of cargo capacity. It’s just large enough to hold a pump, tools, a couple of tubes, some food and a light jacket without feeling cumbersome.

Pros: Comfortable fit, packed with thoughtful features

Cons: Tool compartment too small to hold all essential maintenance items

The Raptor 10 sits comfortably on the wearer’s back and is reasonably well-ventilated, thanks to a combination of pads and mesh that comprise the back panel. The shoulder straps are constructed from perforated foam for additional ventilation as well. 

Included with the Raptor 10 is Osprey’s 3-liter (100oz) reservoir with an integrated handle to make refilling a breeze. The handle also gives the bladder some structure to keep it from ‘sausaging’ when full.

Unlike Camelback, Osprey does not use a quick disconnect system for the hose. Instead, the company has focused on making installation and removal of the bladder easier through the use of a clever zipper layout, called Direct Access. There’s no need to thread the hose through a tiny port, all the user needs to do properly position the hose is zip the hydration compartment closed. It’s the most user-friendly system we’ve encountered, provided you run your hose on the right side.

Aside from the dedicated bladder compartment, the Raptor 10 is divided into a large main compartment; a small upper compartment suitable for sunglasses or goggles that houses a small zippered pocket for a wallet and keys; an external stash pouch for rain jacket or extra layers; a tool compartment with a tool roll; and two zippered waist pockets large enough to carry a couple energy bars, a phone or a point-and-shoot camera.

The separate tool compartment is a good idea, though the fact that it’s too small to carry essentials such as a shock pump and most handpumps means you’ll still need to unzip the main compartment for many trailside repairs:

The lower zippered compartment is designed to be a dedicated tool storage area. Inside the tool compartment is a removable a tool roll with zippered pockets. In use, it’s a great way to keep many of your tools separate from the rest of your gear; however, the compartment is too narrow to hold items such as a shock pump and most hand pumps. You’ll likely have to keep your back-up inner tubes in the main compartment as well. While there are places in the main compartment for all these items, this means you’ll need to open multiple compartments within the pack to access all the tools you need for some trailside fixes.

While this pack has the all essentials of most other trail packs, it’s the small creature comforts that set the Raptor 10 ahead of the competition. Osprey’s LidLock is an oval shaped piece of plastic that passes through a vent on the top of your helmet and is held in place by elastic cord. It’s a nice touch that makes transporting your gear that much easier.

Of all the details osprey includes in its packs, perhaps the most useful is the magnetic hose holder that’s mounted to the sternum strap:

Of all the details Osprey includes in its packs, perhaps the most useful is the magnetic hose holder that’s mounted to the sternum strap. There’s no fussing with trying to tuck the hose out of the way to keep it from flopping around in front of you while you ride; it just stays put.

Verdict: The Osprey Raptor 10 is well-designed pack that is ideally suited to mountain bike rides lasting 2-4 hours.

The separate tool compartment is a good idea, though the fact that it’s too small to carry essentials such as a shock pump and most handpumps means you’ll still need to unzip the main compartment for many trailside repairs.

Despite this shortcoming, the excellent fit and numerous creature comforts make the Raptor 10 the first pack this reviewer reaches for when hitting the trails.
