Mountain Flex HD | 2026

Sporting 40 grams of synthetic PrimaLoft insulation, the Mountain Flex HD will keep you warm without feeling bulky or overbuilt. On the skin track, it breathes well thanks to a stretch-knit liner and Salomon’s venting system, which dumps heat before you start sweating. The DWR-treated ripstop shell shrugs off mist and light snow so you stay dry lap after lap and a cinchable hood adds extra protection from the elements. It’s the kind of jacket you reach for when a puffy feels like too much but you want just a little bit of extra warmth.
