A merino wool performance henley for men that never itches and stays fresh no matter how many miles you put on it
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. The ultimate travel shirt in our arsenal, it does just as well as a merino wool base layer as it does on its own as a performance henley—perfect for adventures that call for packing light and staying comfortable. Even after 72+ hours of constant wear, it’ll still pass the smell test thanks to the naturally odor-resistant and moisture-wicking properties of merino wool.
- Cut from Proof’s premium 72 Hour merino fabric that combines unmatched comfort with technical performance
- Three-button placket at neck with low-profile metal snaps in a matte black finish
- Engineered fabric harnesses the incredible natural properties of merino wool to wick moisture, resist odors, and regulate temperature
- Nylon reinforcement allows the merino fabric to be machine washed while retaining its shape for easy care throughout the life of the garment
- Made in Indonesia with 16.5 micron wool sourced from New Zealand
- 89% 16.5 micron merino wool, 11% nylon
- Temperature regulating
- Odor-resistant
- Moisture-wicking
- Machine washable
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 Henley 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 team at Proof created a collection of performance shirts that can be worn for 72 hours straight without showing any signs of wear—or, you know, odor. The 72-Hour collection is built from the softest and strongest merino wool on the planet. To back up that claim, we’ve packed a merino wool tee 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 layer isn’t just for travel, it’s also our all-time bestselling shirt for everyday wear.
