We worked closely with mountain pros to develop this jacket, built to take you all the way whether you’re skiing, trekking or mountaineering. A feat of textile engineering, LIFA INFINITY PRO™ is built from a three-layer fabric construction using Helly Hansen’s proprietary LIFA® technology, which offers inherent long-lasting water repellency without chemicals. This shell delivers exceptional breathability, protection and durability. This jacket takes design inspiration from our award-winning shell jackets of the past and integrates the function and features you've come to love.
