As a tank top at work for protection and moisture wicking. They have good compression so I wear them in and out of the gym as well. The material is soft and light. Doesn't twist your tummy when worn, which can sometimes happen when other shirts like this don't have enough compression fit for your body. I am planning to buy another pack, maybe a size up just to see the difference as I get older from the gym. Exact size description but also. I went average and I am the exact size of the model's weight and height. Very happy with the quality and quantity for the price.
