The Oversized Boxy T-shirt is an oversized, relaxed style. The fit is much looser and more boxy than our regular T-shirts. The neckline is the same as our Core T-shirts but with a slouchier sleeve. It's made using 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 Cobalt Blue color was created using a recycled water system.
