SmartWool Midweight Zip T-Shirt - Long-Sleeve - Men's

Wear the SmartWool Men's Midweight Zip-T long-sleeve shirt for stop-and-go aerobic activities or as a warm base layer. This top is ideal for situations where the weather and temperature fluctuate, like in alpine environments. SmartWool's porous natural fibers move moisture while it is still in vapor form before it has a chance to condense on your skin; you stay drier and more comfortable throughout your alpine foray. By comparison, synthetics transport moisture after it condenses; you must visibly sweat before any moisture management begins, which leads to chills once you stop moving. SmartWool fiber is also highly adaptable to a broad range of conditions; it keeps you warm when you rest and cool when your pulse and core temperature heat up. This naturally anti-microbial shirt features a -length Zip-T collar for increased ventilation control. Flatlock-seam construction reduces chafing, and an active fit allows for bulk-free layering that doesn't inhibit your freedom of movement.
