VELTHEA™ THERMAL SET
You hate being cold. You hate looking bulky more.
Traditional thermals feel like wearing a carpet — scratchy, stiff, and sweaty by noon.
Layer enough to stay warm and suddenly your outfit is two sizes bigger.
Synthetic thermals cling, spark, and hold moisture against your skin all day.
Heat-lock warmth in a 0.5mm layer
Heat-locking knit
Brushed inner layer traps body heat in a fabric thinner than a t-shirt.
Bare-feel, zero itch
81% nylon + 19% spandex with a water-free soft finish — no wool, no scratch.
4-way stretch, seamless
Moves with you — no seams digging in, no riding up.
Invisible under anything
Slim enough for office shirts, dresses, and skinny jeans.
From office to slopes
Office
