Columbia Men's Zero Rules™ Short Sleeve Tee Carbon

The Columbia Zero Rules™ t-shirt is a super-cooling tech tee with stretch and sun protection. This soft and lightweight men's shirt sports Columbia's industry-leading Omni-Freeze ZERO Ice™ cooling technology, which reacts with your sweat to lower the material's temperature and keep you cool during dynamic aerobic activity in the heat. It also features Omni-Wick™, an enhanced wicking technology that moves moisture away from the skin and onto the fabric surface for rapid evaporation, helping you stay dry and comfortable. The fabric material provides UPF 30 protection from the sun, and has an antimicrobial treatment to protect from bacterial growth.
