HEAT-TRAPPING: Our sauna top is made of an advanced fabric composition that includes spandex, polyurethane, and polyester. Additionally, the inner lining is predominantly comprised of polyurethane, which acts as an excellent thermal insulator. COMFORT: Our sauna suit offers the same level of comfort as regular workout clothes and can be worn directly against the skin. The material is remarkably lightweight, providing ease of movement, while its flexibility and stretchiness ensure a comfortable fit. BODY SLIMMING: Our sweat suit is designed to be tight. It will tuck your tummy in, shape your waist, and accentuate your curves. It will train you not to relax your tummy while wearing it. Please refer to our sizing guide for accurate measurement
