Columbia Women's Base Layer Midweight Long-Sleeve Top

The midweight Base Layer Top offers maximum warmth, minimum weight, and zoned performance for optimal comfort in extreme winter conditions. Omni-Heat thermal reflective lining regulates temperature by retaining body heat while allowing moisture and excess heat to escape. Traps body heat without adding bulk, yet still retains supreme breathability. Omni-Wick advanced evaporation technology offers ultimate moisture management for outdoor activities. 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. Fits close to the body for easy layering. 86% polyester, 14% elastane fabric. Imported.
