Slim fit: This garment fits close to the body for a more streamlined look. Harnessing three different technologies, the FUTUREFLEECE™ Hybrid Jacket isn't just any midlayer. The body features FUTUREFLEECE, a fabric with an exceptional warmth-to-weight ratio and enhanced breathability. The front panel uses FlashDry™ for quick-drying, sweat-wicking protection. Then there's the front body, which harnesses Ventrix™ technology where small perforations in key zones open with movement, allowing excess heat and perspiration to escape while remaining closed in times of rest to retain body heat. Put them together, and you'll stay just-right warm and dry all hike long.
