Columbia Titan Ultra Half Zip Shirt Men's

Taking design inspiration from the running savants at Montrail footwear, the Columbia Men's Titan Ultra Half Zip Shirt is a lightweight layering piece for demanding trail runs and daily jogs around the park. Omni Freeze Zero employs a sweat activated cooling treatment, allowing you to run farther and faster without overheating. It's designed with an active fit that sits closely without inhibiting necessary movements for blasting down the trail. Going one step further for running comfort, the lightweight polyester fabric pulls moisture off your body for rapid evaporation. Its half length zipper allows you to dump excess warmth at a moment's notice, should the cool, crisp morning give way to a sunny afternoon sky. And to ensure it doesn't smell like an old shoe after you're finished, the antimicrobial treatment fends off funky odors from taking residency.
