The Exercere Oversize Tee is made from cotton with a crew neck for softness and comfort. Our t-shirts are made in box fit (oversized) & unisex design. The sizes are normal in the sense that if you normally wear S or M, we recommend an S/M if you want an oversized fit. Under 'details' you can see what size the model is wearing. It's the perfect t-shirt that can work both for everyday wear or as a cover up for training.
