Flarixa Seamless Thermal Underwear Set for Women — Long Sleeve Top & Long Johns (Base Layer)

Lightweight, soft and warm — the first thermal layer that keeps you cosy all winter without bulk.

The Flarixa Seamless Thermal Set is a lightweight yet effective base layer designed to be worn directly under your clothes. This two-piece set — a long-sleeve top and long johns — fits like a second skin, helping your body retain warmth while remaining breathable and comfortable throughout the day.

Thanks to its seamless, stretch fabric, it does not dig in, itch or show under clothing. Ideal for everyday wear — whether at work, at home, on winter walks, travelling or as a base layer for cold-weather activities.

“The thermal layer you barely notice — except that you stay warm.”
