POLARMAX Active Stretch Base Layer Midweight Women’s Bottom — Midweight Thermal Bottom (polyester/spandex stretch knit)
Warmth that moves with you—women’s-specific fit for dry, flexible comfort in cold conditions.
This POLARMAX Active Stretch women’s midweight bottom uses a 4-way stretch, moisture-wicking polyester/spandex knit to retain heat without bulk. The brushed interior traps warmth, while the smooth exterior layers cleanly under pants or bibs. Designed with a women’s pattern for better rise, hip, and waist fit, it delivers all-day comfort that keeps up with work or winter play.
Product Description
A premium, active-stretch thermal bottom made to balance warmth, breathability, and mobility. The brushed-back interior feels soft against skin, flatlock seams help prevent chafing, and the wide elastic waistband stays put without pinching. An anti-odor finish and quick-dry fibers support repeat wear and faster turnarounds between outings.
