Simms Midstream Wool Insulated Pant

Stay warm, move freely, and keep your kit streamlined with insulated pants built for travel, daily wear, and backcountry missions. Harnessing the natural performance of wool, these pants deliver reliable warmth, breathability, and exceptional odor resistance across a wide range of temperatures and humidity—perfect for chilly camps, damp days, and year-round adventures.

The core is Lavalan® Sport 40G wool lofted insulation, a renewable solution that manages temperature and moisture without bulk. Abrasion-resistant nylon fabrics on the face and liner feature a C0 DWR finish for light water resistance, while durable overlays at the knees and seat add extra protection where it counts. An integrated belt with a quick-release buckle and an elastic waistband creates a secure, comfortable fit you can dial in on the go.

Designed for movement, the articulated knee and gusseted construction enhance mobility whether you’re hiking, casting, or setting up camp. Practical pocketing keeps essentials close, with two front drop-in hand pockets and two rear drop-in pockets, and a zip fly for everyday ease. From extended travel to off-season layering, these versatile insulated pants bring back the cozy when conditions turn cold and damp.
