"Sweat Shaper" is a compression garment that is designed to enhance performance during exercise and increase sweat production. It is made from a special blend of performance compression and polymer fabrics. The product is said to do two things very well: accelerate sweating and provide compression. The inner lining of the "Sweat Shaper" is made with polyurethane instead of neoprene, which promotes sweat as much or more than neoprene, while being thinner and more comfortable to wear. The polyester/spandex outer shell combined with the inner lining makes it a very good compression shirt. However, while it can help you lose water weight faster by increasing the amount you sweat, this is only temporary. The product has received positive reviews from users, with many praising its ability to increase sweat production and its comfortable fit. However, some users have reported issues with sizing and delivery. It's recommended to buy the product from the official "Sweat Shaper" website to avoid counterfeit products.
