The men's SmartWool Merino Sport Fleece Pant will stand up to the cold.

Designers cut the Sport Fleece Pant from super soft Merino for a cozy next-to-skin feel, and they wrapped it in a durable synthetic outer material to deliver additional protection from the elements.

A windproof front panel fights the icy winter breeze, and flatlock seams help minimize chafing. Plus, SmartWool sewed in two zippered side pockets so you can securely stash your phone, wallet, keys or any other essentials.

With an athletic fit that’s tailored for performance, the men's SmartWool Merino Sport Fleece Pant is a perfect match for a cold winter workout—or a marathon movie session on the couch.
