Merino Wool

We've updated our Men's Merino 250 Base Layers Bottom to bring you a better fitting, more functional tight. The technical benefits of 100% Merino wool will help you keep your game at a high level for longer. And our warmest-weight wool fabric will help keep you warm and comfortable as you ski, run, and hike the day away.

Smartwool is printing a pattern on their Men's Merino 150 Print Boxer Briefs— bringing you the ultimate in Merino comfort with a fun, mountain-inspired design. The Core Spun technology beefs up garment durability without sacrificing next-to-skin comfort by wrapping high-quality, super-soft Merino around a nylon core for every thread in our 150 fabric. The wide, Merino-lined elastic waistband and flatlock seam construction will help make these boxers your new favorite for any activity—from urban exploration to finding adventure on new trails.

Comfort is never a question when it comes to the Men's Merino Sport Wind Boxer Brief. Experience the best of both worlds with the comfort of Merino and the durability of recycled polyester. Plus, the added windproof front panel increases protection from the elements, so every adventure starts and ends comfortably.
