Gore's Fusion Cosmo might sound like a cocktail, but it's actually the latest addition to its softshell range, and much more at home on the trail.
Although it's pitched as a dedicated mountain bike jacket, the fine cut and sublime fit mean it's actually a capable accomplice on any kind of bike. Zip it up and it snugs into your chest without feeling tight. The inner elastic cuffs feature thumb loops so, when it's paired with gloves, there's no gap for wind or rain.
The Fusion Cosmo has held up to some very wet and cold rides. The softshell exterior puts up a respectable fight against rain, and water beads off for a decent length of time before it starts to get saturated. It's also shrugged off frequent muddy crashes, which we obviously only had in the name of testing and not because we did anything stupid. Obviously.
The waist and underarm zipped vents work well when things get hot (or smelly), the side vents double as pockets and there's a large rear pocket, plus a chest compartment. The reflective detailing does its job well too.
The fleece lining is warm and the button-away luminous shirt tail takes care of road spray. Our only criticism is that the elastic inner cuffs can snag when getting it on and off. For reliability and all-round autumn and winter performance, the Fusion is a potent cocktail.
