Simms Men's Heavyweight Fleece Lined Baselayer Bottom - Black
The Simms Men's Heavyweight Baselayer Bottom in Black is built for maximum warmth and freedom of movement in cold conditions. Made from stretch micro grid fleece, these bottoms trap heat close to the skin while wicking moisture away so you stay dry and comfortable during long days on the water.
- Stretch micro grid fleece for thermal retention and unrestricted mobility
- Moisture-wicking, quick-dry construction sheds light rain and splashes
- Anti-odor technology helps control odors caused by microorganisms
- Strategic stretch panels allow easy integration with socks, waders, bibs, and boots
- Designed to function as a primary base layer or layered over lightweight baselayers
Built for anglers and other cold-weather outdoor activities, these baselayer bottoms perform when warmth and range of motion matter most — from shore fishing in a chill wind to long hours in a boat. The streamlined fit minimizes bulk under outerwear while the stretch panels make dressing and movement easier.
Pair with mid- or heavyweight Simms baselayer tops and your preferred outer layers for comprehensive cold-weather protection.
