POLARMAX Active Stretch Performance Base Layer Midweight Men’s Top — Midweight Crew (polyester/spandex stretch knit)
Warmth that moves with you—built to keep you dry, flexible, and comfortable in cold conditions.
This 4-way-stretch POLARMAX midweight base layer top (crew neck) is crafted from a moisture-wicking performance knit and built for active cold-weather wear. Featuring a brushed interior for warmth and a smooth exterior that layers cleanly, it delivers a mobile, close-to-body fit for long days on the job or in the field.
Product Description
A premium, active-stretch base layer made from a quick-dry polyester/spandex knit for dependable warmth, breathability, and mobility. The brushed inner face traps heat; the smooth outer face slides easily under hoodies, bibs, and jackets. Flatlock seams reduce chafe, while an anti-odor finish helps keep you fresh through repeat wears.
