## Summary
Slim fit navy blue merino wool blend t-shirt with a crew neck, designed for moisture-wicking and temperature regulation.
## Description
Our bestselling 72-Hour T-shirt is the merino tee, reinvented to help us go farther and pack lighter. Woven from a super-soft, Woolmark-certified merino wool blend, it naturally wicks moisture, regulates your temperature, and stays fresh even after 72+ hours of constant wear. We’ve packed it—and just it—for three-day camping trips to Bishop, California, with our Creative Director, Alex Souza, and then worn the same one underneath a blazer while on the road.
