Setting off on your bike for adventure is a thrill, with just the bare minimum packed and a spirit of exploration. However, the weather can often be hard to predict - here the lightweight GV500 Waterproof Jacket ensures you have wet-weather protection to hand should conditions take a turn for the worse. Thanks to ExoShell40 3-Layer waterproof fabric, the GV500 is rated 20,000mm for waterproofing. Along with a fully seam-sealed construction and a water-repellent surface finish, this should keep the worst of the wet weather out for prolonged periods of riding. Despite the excellent wet weather protection, it's also a remarkably light and easy-to-pack jacket. Ideal to stuff into a frame bag or saddlebag, it's ready to pull on when you experience wet weather on a multi-day bike-packing trip. Just as important for comfort on the bike is excellent breathability. And the outstanding breathability rating of 40000g/m2/24hr ensures even higher-tempo cycling efforts won't leave you soaked in sweat. You'll also benefit from the athletic fit. On a long day in the saddle, this ensures no wasted effort in battling a flapping jacket. Lastly, reflective details ensure you're easier to spot when setting off from camp in the low light of morning or when your adventures stretch into the darker skies of the evening.
