The Flux Superlight Softshell jacket does exactly what it says on the tin; it’s super light, has excellent waterproofing, and packs itself into a space not much bigger than two handfuls.

Constructed from the award-winning ‘P4DRY’ fabric which uses recycled coffee grounds to create a layer that absorbs odour and aids breathability, the jacket has four-way stretch properties while still boasting 20,000mm of waterproofing and 30,000gms of breathability. That’s as much as most waterproof cycling coats, but the Flux has the added benefit of being a stretchy pac-a-mac.
And if this wasn’t enough, it also crams in hem and hood draw-cords, laser-cut underarm venting, a silicone print over the shoulders to prevent backpacks from sliding around, oh, and a limited lifetime warranty from Madison.
My favourite extra, however, is the adjustable hood, which is thin enough to sit underneath the helmet, but stretchy enough to go over the top as well. The hood also stows away under a buttoned flap to prevent the parachute effect when not in use.
The Flux in action
The small size Flux fitted me well (I’m a UK/AU10 or US6). It’s slimmer on the arms than I’m used to, but the four-way stretch never allowed me to notice this on the bike. The cuffs even accommodated my larger waterproof gloves.
It’s not the kind of jacket that would easily accommodate a thick winter jersey or too many layers, but if you tend to ride in minimal winter clothing anyway, such as a long-sleeved jersey or Merino jumper, then the Flux is a nice addition to the backpack for getting you through any sudden weather changes on the trail.
This little Flux was tested in warm showers and cold rains, and it easily squeezed into a backpack waiting for its time to shine on all other occasions.
I never once wondered if I could get away with not packing it, it’s so small and light that it was barely a burden on the backpack. On the trail and in the rain, the jacket moved exceptionally well. Even with the hood up, I could turn my head without it popping off, and I felt as free as if I weren’t wearing it at all.
When working up a sweat, the jacket did have a slight clammy feel, but no more than the usual lightweight pac-a-mac. Despite the breathability boastings, I still found it to be stuffy.
I may not choose to go out riding in this jacket if I knew the ride would be wet all day, but I certainly wouldn’t feel burdened if I had to put it on during the middle of a ride to escape a storm.
