Our bestselling 72-Hour Tee is woven from a super-soft merino wool blend that harnesses the material's all-natural performance, while also offering long-lasting durability and machine-washable convenience. This high-performance shirt is built for everyday style, no-hassle travel, and casual days outdoors. Even after 72+ hours of constant wear, it’ll still look on-point and pass the "sniff test" thanks to the naturally odor-resistant and moisture-wicking properties. Our community has wear-tested these tees everywhere from the streets of Tokyo to the trails here in Austin, and we can’t wait to hear where you take yours.
