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 three days of constant wear, the 72-Hour T-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 T-Shirt 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 team at Proof created a performance t-shirt that can be worn for 72 hours straight without showing any signs of wear—or, you know, odor. The 72-Hour T-Shirt 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 shirt isn’t just for travel, it’s also our all-time bestselling t-shirt for everyday wear.
“I wore this to Seattle and back and then up to Maine. Zero odor and still looked fresh.”
