From breaking trail on mid-winter ski tours to blistering desert hikes in summer, the Icebreaker Men's Bodyfit 150-Ultralite Anatomica Long Boxers deliver comfortable performance through every season. Merino wool naturally regulates temperature and resists odor, and it's blended with nylon for moisture management and durability, along with Lycra for flexibility. The contoured pouch offers support, and flatlock seams won't chafe or cause rashes.
