How to Measure - Chest: Measure straight across from edge to edge, starting 1" below the armhole, multiply by 2 - Shoulder: Measure straight across from shoulder seam to shoulder seam. Again, it’s easiest to measure across the back of the garment. - Body Length: Start at the top of the shoulder where it meets the neck seam, and measure straight down to the hem. - Sleeve Length: Start at the center of the back of the neck, measure straight across to the shoulder seam, and then follow the edge of the garment to the cuff. Pro tip: it’s easiest to measure across the back of the sleeve.

About the 72-Hour Collection

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.
