A highly breathable and insulating mid-layer designed to be worn over the Chinook Merino Bottom and beneath pants during cold hunting conditions. It complements well with the M7 Pant in active, late-season, snowy conditions. Enhancing Stone Glacier's cold weather mid-layer bottom, this version comes equipped with full-leg zips and a Velcro waist closure, facilitating easy on/off in the field without the need to remove pants or boots. The front-forward placement of side zips eliminates hot spots under pants and a pack. Additionally, it seamlessly integrates with all Stratum Layered Zipper System pants in the SG line, enabling instant ventilation from skin to shell. Notably, a new zippered fly adds convenience for bathroom breaks. Features & Specs: Weight: 10.2 oz.
