We've created a T-shirt that's tightly woven, thick, and yet quick-drying, with a smooth, dry feel. For an "outdoor T-shirt," durability, thickness, and a firm, dry texture are essential. Until now, we've made them from 100% cotton, but the weight and slow drying time were challenges. By switching to a cotton-polyester blend with a moisture-wicking and quick-drying finish, we've come much closer to our ideal. We're really looking forward to everyone trying this T-shirt.
