The Columbia Cuerpo Thermo II Half-Zip Pullover boasts an exquisite hybrid of warmth, stretch-infused comfort, and sweat-wicking breathability. Ultra-cozy 100% polyester Thermo Heat fleece shell fabric is bolstered with Columbia's exclusive Omni-Heat thermal reflective technology - at the front and back torso and tops of the arms - which reflects and retains body heat for exceptional warmth and temperature regulation. Four-way stretch panels at the sides, underarms, and back neck - made from a 92% polyester, 8% elastane Thermo Stretch fabric blend - feature Omni-Wick EVAP technology, which disperses sweat quickly across a broad surface area for accelerated evaporation. Articulated elbows allow a full range of motion in the arms for even greater comfort. The half-length front zipper extends through the top of the low-profile, mock-neck collar for added protection against chilly air. A zip-closed pocket at the left chest offers convenient storage for your small essentials. Active fit. Imported.
