The team at Proof created a collection of performance wear 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 packed a merino wool tee from the collection 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.
