columbia baselayer long sleeve ladies midweight top.

What’s next to your skin sets the stage for your comfort: don’t mess around. Developed with top physiologists, Columbia’s new base layer series offers maximum warmth, minimum weight, and zoned performance for optimal comfort.

Our bodymapped design keeps you warm and dry in all the right spots by placing Omni-Heat® reflective dots in zones that need warmth most, and Omni-Wick™ in high-perspiration zones for maximum moisture transmission. Antimicrobial treatment keeps the fabric feeling (and smelling) fresh during high-exertion activities. Highly stretchable, with flat-lock stitching to avoid chafing and raglan sleeves for extended range of motion, this midweight top sets you up for success.
