The Smartwool Snowboard Full Cushion Cold Canyon OTC Sock packs full cushioning into a sock that weighs in at just 3. 95 ounces, delivering real warmth without crowding a snowboard boot. Indestructawool(TM) reinforces the zones that see the most wear, and a Virtually Seamless(TM) toe removes the seam that usually causes friction over a long day. The 4 Degree(TM) Elite Fit System keeps everything locked in with strategic stretch and mesh zones, while merino wool naturally regulates temperature, moisture, and odor. What Our Gearhead(R) Experts Are Saying:"I've sat through enough cold chairlift rides to know when a sock is actually keeping my feet warm versus just feeling thick, and this one keeps the cold out without ever feeling like it's stuffing my boot. Full cushion doesn't have to mean bulky."
