"What Our Gearhead® Experts Are Saying: ""I wore the Mountain Flex Jacket on a frosty pre-dawn ridge scramble and was seriously impressed by how well it managed heat and moisture. The synthetic insulation kept me warm during rest breaks, but the breathable stretch liner and ClimateSync venting kept things dry on the move. It’s that rare midlayer you can leave on all day.""For high-output winter pursuits, we need a layer that works as hard as we do—and the Mountain Flex Insulated Hooded Jacket delivers on every front. Built for dynamic movement in cold temps, it features lightweight synthetic PrimaLoft insulation wrapped in a weather-resistant ripstop shell that keeps out light precipitation and wind. Inside, a breathable stretch-knit liner and Salomon’s venting technology manage sweat and heat as intensity climbs, letting us stay comfortable whether we’re grinding uphill or dropping into frosty descents. The athletic yet regular fit layers easily under a shell or stands alone for fast-paced missions."
