The Slim Fit T-shirt is a fitted style with a small capped sleeve and a boxy cut, designed to be close fitting to the body. If you prefer a more relaxed fit, please size up. It's made with saltwater Seaweed Fiber, Organic Cotton and treated with our trademark technology: PPRMINT™ oil. PPRMINT™ has natural antibacterial and antimicrobial properties to keep your T-shirt fresh for longer, meaning it can be washed less often—saving water, energy and time. The Ultra Violet color was created using Environmentally Friendly Dyes and a recycled water system.
