With the release Berghaus VapourLight Hyper Smock 2.0, we now see a new reigning champ claiming the title as the world's lightest waterproof jacket. Who was the previous champ? Well, that would be the first generation model, of course. With ultra-marathoners, trail runners, mountain bikers, hikers, and commuters in mind the Berghaus VapourLight Hyper Smock 2.0 is driven by athletes looking for lightweight performance. Every aspect of design was considered, from using exclusive ultra-lightweight seam tape, to a closer fitting hood to reduce drag and flapping, and a reinforced chest pocket, this jacket has everything you need and nothing you don't. Weighing in at 2.6oz - that's a full ounce lighter than a deck of cards - this smock sees the use of the brand's own innovative super-lightweight Hydroshell Hyper fabric with elastic cuffs and hem for a comfortable, secure fit. Arriving in its own stuff sack, there's no reason not to be ready for Mother Nature's worst. Available now in three colorways from Berghaus.
