Assos Ultraz 3/3 Fugu Socks

An all-new, ultra-insulated winter sock platform, engineered with a wool textile blend and reinforced with increased insulation in critical areas. Breathable, ultrasoft, and warm total comfort for winters harshest conditions.

The Ultraz FUGU hearkens back to the warmest, most protective line of winter equipment in ASSOS history, so itÕs fitting to bring back for our most thermoregulating socks. The wool blend creates micropockets of warm air beneath the protective layer of your booties, with increased insulation across the toe and the front of the sock. The ultra-high 31cm (16in) cuff extends that protection to eliminate gaps between the FUGU and winter tights.
