Simms Men’s Thermal Bottoms are the warmest mid-layer bottom the company makes for cold air, wading into frigid streams or on the hard water when ice fishing. A grid-fleece interior traps heat next to your skin without adding bulk or limiting your range of motion. The tapered hem streamlines the fit for easier layering and more comfort. Simms Thermal Bottoms are also sewn with a patterned gusseted crotch to make layering with bibs and waders easier, too. Double-slash handwarmer pockets and a self-fabric waistband with dual-snap closure and zippered fly are convenient. With all of the features built into this mid-layer, you won’t be chilled to the bone when you don a pair of Simms Men’s Thermal Bottoms!
