The Mountain Flex Hood combines PrimaLoft insulation fiber with an exceptionally breathable fabric. Thanks to ClimateSync technology, the moisture generated during activity is able to evaporate, so the jacket doesnt feel stifling. ClimateSync is based on star-shaped cuts in the insulation material, which allow more air and moisture to pass through the harder you move. The Mountain Flex Hood works well for active movement in cold and cool weather, but also as a lightweight insulating jacket for hikers, long-distance runners during breaks, or even as part of sporty everyday wear. - Regular fit - Lightweight yet durable ripstop outer fabric - Technical insulation fiber - Reflective details - Zippered side pockets - Adjustable hem and hood
