I have worn this maybe two times. I bought this in my other sauna suit with the intention to use it way more but I don't sauna enough to use them. I love this style and fit though!! Sauna suit is very thin material like windbreaker but the silver interior does raise your body temperature to sweat. Exercise sweat shirt for women can raise your body temperature immediately, burning 5 times calories, adds enhanced sweating and makes working out more meaningful and effective.
