Columbia Sportswear Baselayer Midweight 1/2-Zip Top - What’s next to your skin sets the stage for your comfort: don’t mess around. Developed with top physiologists, Columbia’s new baselayer 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, while a deep neck zipper helps you moderate heat when you need to. 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.
- Antimicrobial treatment prevents the fabric from accumulating odors over time
- Slim, form-fitting design reduces excess fabric bulk for an athletic look
- Omni-Wick fabric's blend of polyester and four-way-stretch elastane provides a comfortable feel that wicks sweat and keeps your body temperature regulated
