Simms Thermal Midlayer 1/4 Zip Top - Men's

Simms warmest midlayer for cold days, the M's Thermal 1/4 Zip Top adds warmth on its own, or layer it under your favorite jacket to dial in reliable comfort. A grid-fleece interior traps heat next to-skin without adding bulk or limiting range of motion, and a smooth exterior makes for seamless layering.
