L/S HOT Crew in black, XL size, with excellent heat retention. - Brand: THE NORTH FACE - Model Name: L/S HOT Crew - Size: XL - Color: Black - Features: Thermo function with excellent heat retention When exposed to cold, simply insulating with underwear isn't the right choice. Properly managing the sweat you produce is also a crucial issue, and comfort is only achieved by addressing both. This HOT series uses polypropylene, which doesn't absorb water, on the skin-facing side to suppress chilling from sweat. Sweat is absorbed by polyester and evaporates. Then, the thick, brushed & KODENSHI® Thermastat fabric generates ideal heat retention. The regular price is 7480 yen, but it's currently out of stock on all websites, so this is the price.
