The new Geon Jacket is a true all-mountain fleece. Built as a breathable midlayer for high-energy cold-weather use, it is equally practical for walking in the hills and for easy-boost insulation during your post-climb downtime The Geon Jacket is a mid-weight stretch fleece, designed to provide low-bulk layering insulation for cold-weather climbing, scrambling and hiking. Built from our polyester-based Thermic™ fabric, it combines inherent hydrophobic properties with outstanding breathability to help move moisture through the layers and away from your skin. A brushed grid backer increases strength, comfort and warmth retention and, with its athletic fit and low-bulk flatlock seams, the Geon Jacket will also sit very comfortably between a base layer and a shell. Additional mountain features include a pair of discreet, harness-compatible YKK® zipped hand pockets and a full-length YKK® front zip so you can adjust your ventilation on the move. With its active style, features and colour options, the Geon Jacket is an authentic mountain midlayer that is equally comfortable as a three-season everyday outer. .
