Smartwool Mid 250 Crew - Men's

There's nothing like seeing a sunrise from the top of a four-thousand footer, but the only thing that gets us out of our sleeping bags that early is the sure comfort of a quality baselayer. That means the Men's Merino 250 Base Layer Crew from Smartwool. The Mid 250 fabric, Smartwool's warmest baselayer, both retains heat and breathes well to provide efficient thermoregulation. It also serves as a single layer in cooler weather. Shoulder panels eliminate top shoulder seams, eliminating distress from backpack shoulder harnesses, and flatlock seam construction eliminates chafing.
