Simms Midstream Wool Insulated Vest

Built for changing conditions on the water and beyond, this mid-weight puffy vest delivers reliable warmth, breathability, and packable convenience without the bulk. Powered by Lavalan® Sport 60G wool lofted insulation, it leverages wool’s natural temperature regulation and moisture management to keep you comfortable across wide-ranging weather and activity levels — with exceptional odor resistance for travel, daily wear, and extended backcountry stays.

Abrasion-resistant nylon textiles on both the face and liner add durability, while a C0 DWR finish sheds light moisture to help keep you dry in damp conditions. Smart storage keeps essentials close: a YKK conceal-zippered chest pocket, two concealed-zippered hand pockets, and an interior mesh dump pocket that doubles as a self-stow pouch for compact carry. A drawcord adjustable hem seals in warmth and fine-tunes the fit when the wind picks up.

From chilly dawn launches to cool evenings in camp, this versatile insulating layer streamlines your kit and extends your time outside with dependable performance and all-day comfort.
