Berghaus continues to push the boundaries of just how light a jacket can be while still remaining completely waterproof. The new VapourLight Hyper Jacket is a full-zip version of the company’s popular Hyper Smock. Both use Berghaus’ proprietary HydroShell Hyper fabrics, which are billed as the lightest 100% waterproof materials on the market. Tipping the scales at a mere 3.52 oz, the Hyper Jacket comes equipped with its own stuff sack, making it highly packable. With this size and performance, it looks like it could be the kind of jacket you’ll want with you on all of your outdoor adventures. The VapourLight Hyper Jacket will cost $155.
