In the backcountry fun and safety are our top priorities but comfort is a close competitor so we created the Hybrid Grid Fleece Pullover for best-of-both-worlds-style thermal management. This techy midlayer uses two fleece types: a cozy polar fleece that traps heat at the core in chilly conditions and a grid fleece that wicks moisture and allows airflow on our most intense hikes. We recently updated this design with action-ready fit improvements and a new vertical half-zip that improve our performance by enhancing comfort and mobility on the mountain.
