Professional design: Sweat Body Shaper Vest for Men is lightweight, odor-free, and half the weight of traditional sauna vests, providing effective sweat activation while remaining dry on the outside. This men's compression t-shirt is compact and easy to pack in a gym bag, making it ideal for gym workouts, outdoor activities, and daily wear. Advanced fabrication: Made with 92% polyester and 8% spandex, this sauna vest features two layers. The inner thermogenic fabric helps increase body temperature to support fat burning, while the outer compression layer provides shaping and a streamlined silhouette. Sauna effect: The heat-trapping design creates a sauna-like experience, promoting sweating during physical activity, helping to accelerate calorie burn, support circulation, and assist in detoxification through increased perspiration. Body shaper: This workout sauna tank top offers targeted compression for the abdomen, love handles, and back, providing tummy control, improved posture, and a flatter, more contoured appearance. Comfortable wear: Designed to move with the body, this tank top offers a comfortable fit for daily use and is easy to clean. With a classic tank top style, it can be worn discreetly under clothing without adding bulk.
