Merino wool men’s t-shirts that never itch and stay fresh no matter how many miles you put on them
Our bestselling 72-Hour collection is crafted from a New Zealand merino wool that’s infused with nylon to ensure it never shrinks in the washing machine. As the ultimate travel t-shirt in our arsenal, it functions just as well as a merino wool base layer for adventures that call for packing light and staying comfortable. Even after 72+ hours of constant wear, this shirt still pass the smell test thanks to the naturally odor-resistant and moisture-wicking properties of merino wool.

Sourced from industry leader Global Merino, the specialized merino/nylon blend used in the 72-Hour Merino Tee is the cutting edge of technical fabrics that doesn’t sacrifice comfort for performance. It not only takes advantage of the amazing natural properties of wool, but strengthens them with nylon for a truly impressive fabric. Sustainably sourced from New Zealand farms (or as kiwis call ‘em, “stations”).
- The 72-Hour Merino Pocket T-Shirt has a slim fit so if you are between sizes or prefer a roomier fit, we recommend the larger size
- If you love the fit out of the box, we'd recommend a cold, gentle wash and air drying or swapping out for one size larger to account for standard shrinkage that comes with machine washing / drying a wool-based product

The 72-Hour Tee is built from the softest and strongest merino wool on the planet. To back up that claim, we’ve packed it as our only shirt on demanding excursions around the world—from Iceland and the Swiss Alps, to Mexico City and even our own backyards. Turns out, this temperature-regulating tee isn’t just for travel, it’s also our all-time bestselling tee for everyday wear.
