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
Brushed inner layer traps body heat in a fabric thinner than a t-shirt.
81% nylon + 19% spandex with a water-free soft finish — no wool, no scratch.
Moves with you — no seams digging in, no riding up.
Slim enough for office shirts, dresses, and skinny jeans.

Sized by weight — not guesswork
Just two sizes, stretch does the rest:
| Size | Weight | Fit |
|---|---|---|
| M–L | 88–143 lb (40–65 kg) | Snug second-skin fit |
| L–XL | 143–198 lb (65–90 kg) | Snug second-skin fit |
Between sizes? Size up for comfort, down for maximum heat-lock.
Wrong size? Free exchange, no questions.
