Just as at home on the road or the trail the Helium jacket offers excellent waterproof protection in a highly packable format. If it looks like there’s a chance of a heaver shower makes sure you have a Helium jacket in your rear pocket. The lightweight 2.5 layer fabric has impressive waterproofing & breathability stats to keep you dry from both within & without. The jacket comes with its own stuff sack to tidily pack it away into a size that’ll stuff into a rear jersey pocket when not in use. The fit is designed to be athletic to stop it from flapping around in the wind & movement is unimpeded with well-placed stretch panels on the hem & armholes. The off-centre front zip means that it won’t rub on your chin when the tall collar is done all the way up. There’s also a drawcord at the back of the neck to cinch it down for a customised fit. Adjustment is automatic at the hem & cuff with the use of stretchy softshell material rather than more draw cords. Visibility in low light conditions is helped with the addition of reflective piping across the shoulders & sleeves. The jacket also features a discrete rear pocket with a zipped closure to keep your valuables safely stored. Technical details Waterproofness: 15000 Breathability: 15000
