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 casual long sleeve t-shirt—perfect for adventures that call for packing light and staying comfortable. Even after three days hours of constant wear, this shirt still passes 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 three New Zealand farms:
|Sleeve: Shoulder to Sleeve Opening||25||25½||26||26½||27||27½|
|Body Length: High Shoulder to Bottom||26¾||27½||28¼||29||29¾||30¾|
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 layer 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, these temperature-regulating styles aren't just for travel, they're also our all-time bestsellers for everyday wear.
