The Columbia Mens Trail Micro Tab is the perfect high-performance no-see-em. The Trail Micro Tab features Merino wool and ultra-comfy Y-tab construction. Merino wool is a miraculous fabric that's naturally sweat-wicking and antimicrobial, and the Y-tab is ultra-comfy. A cush tab in back prevents the sock from getting eaten by your trail shoes, while a scoop in the cuff-line leaves the ankle bone abrasion-free. Cushioning in the heel and toe protects your foot from jarring. A seamless hand-linked toe banishes pressure points and abrasion.
