Tops

This minimalist-style crew is anything but insignificant. It is a lightweight, super-moveable top, perfect for all of your sweatiest cold-weather activities. With Merino Sport yarns and gender-specific ventilation perfectly placed to maximize thermoregulation and breathability in high-intensity activities, it helps amplify moisture management, movement, and comfort.

Zip up and head out this winter with a layer that provides warmth, comfort, and performance—the Men's Merino Sport 250 Long Sleeve 1/4 Zip tee. Smartwool's warmest Merino/poly blend will help move moisture away from skin as you heat up, and it will dry quickly and hold its shape no matter how sweaty you get during your workouts. For even more breathability, they've added gender-specific, body-mapped panels of mesh fabrics. Minimal Merrow seam construction provides superior durability while keeping super-soft material against your skin, and thumb loops provide a secure fit.

Blending the remarkable properties of Merino wool and PRIMALOFT®, this baselayer is designed for active use in cold conditions. Premium Merino wool draws vapour sweat away from the body whilst high quality PRIMALOFT® yarns wick liquid sweat across the outer surface, allowing it to dry quickly.
