The Men's Sawtooth Hybrid Vest sets a new standard in versatility for western and treestand hunters alike. Re-engineering our hybrid technology into a vest configuration, the Sawtooth Hybrid Vest is an excellent layering option for the backcountry. Oriented across the back, our 20.5 micron, midweight 300 Merino-X fabric provides, extreme odor resistance and breathable warmth, allowing for greater airflow where packs and tree trunks typically cause heat and moisture to build. DWR coated nylon panels provide critical durability and water resistance where you need it most--the chest and shoulders. Body-mapped to preserve core body temperature, we've added 60g 37.5 synthetic insulation behind the durable nylon panels in the chest for added insulation and wind resistance.
