The Rab 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 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, 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.
