This Seamless Base Layer Is 65% Warmer Than Regular Underwear, Providing Heat Without the Bulk or Fabric Pilling.

You need serious warmth for the cold season, but traditional thermal wear is often bulky, itchy, and restrictive, making you feel sweaty and uncomfortable. You need a layer that is ultra-thin, moisture-wicking, and shows graceful curves.

But what if your thermal wear could regulate your body temperature to 37 degrees? This is not normal thermal fabric. The mechanism is a Seamless Elastic Thermal Inner Wear made with the latest heat-trapping nano-weave (implied by thermal wear) and a blend including 34% Rayon Fiber.
