Lightweight base layers are a cold weather essential. At Arvada Army Navy Surplus, we offer you excellent quality thermal clothing to regulate your core temperature so that you can comfortably work or play outdoors this winter. Blends of polyester and merino wool make our women’s thermal bottoms and tops last long, keep you dry, and keep you warm all day long. Trap warmth next to your skin where you want it while ventilating excess heat and wicking away moisture with hard-working long underwear from brands like Coldpruf and Terramar Sports. Let us help you stay comfortable whether you find yourself on the slopes, on the job, or on the trails.
