Columbia Men's Base Layer Heavyweight Long-Sleeve Top

This heavyweight Base Layer Top offers the highest warmth-to-weight ratio on the market 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. Supple 85% polyester, 15% elastane fabric has a soft, sueded hand and an antimicrobial treatment to keep it feeling (and smelling) fresh during high-exertion activities. Highly stretchable, with flatlock stitching to avoid chafing, and raglan sleeves for extended range of motion. Fits close to the body for easy layering. Imported.
