Columbia Women’s Baselayer Heavyweight Long Sleeve Top

What’s next to your skin sets the stage for your comfort: don’t mess around. Developed with top physiologists, Columbia’s new heavyweight baselayers offer our highest warmth-to-weight ratio for optimal comfort in extreme winter conditions.

Our innovative bodymapped design keeps you warm and dry by placing Omni-Heat® reflective dots in zones that need warmth most and Omni-Wick™ in high-perspiration zones for maximum moisture transmission. Supple fabric has a soft, sueded hand and an antimicrobial treatment to keep it 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 is the heavyweight champion of cold-weather comfort.

Omni-Heat® – Thermal Comfort Omni-Heat® breakthrough thermal technology helps maintain warmth and prevent heat loss, keeping you comfortable in cold weather. Omni-Heat® ensures you stay warm and comfortable in the most extreme cold conditions.  

OMNI-Wick Omni-Wick® is the ultimate moisture-management technology for the outdoors. Its superior wicking properties move moisture away from the body and enable perspiration to evaporate quickly. During physical activity, increased body temperature causes perspiration (you know: sweat). Normally this results in damp, clammy, and uncomfortable clothing (not to mention unattractive). With Omni- Wick clothing, moisture is quickly wicked up into the fabric, and away from the wearer’s skin. The moisture spreads out across the surface of the fabric where it quickly evaporates. This wicking/evaporation process keeps the wearer cool and the clothing dry. You stay dry, which helps regulate temperature, prevent chafing and keep you comfortable all day. Work up a sweat without getting all wet.
