Merino wool sweater 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 sweater in our arsenal, it’s perfect for adventures that call for packing light and staying comfortable. Even after putting it through the wringer and a couple red-eye flights on an extended trip, it’ll still pass the smell test thanks to the naturally odor-resistant and moisture-wicking properties of merino wool.


  • The perfect travel sweater—stays fresh for 72 hours so you can leave it on all weekend
  • Super versatile crewneck design allows you to dress it up or down with ease
  • Built from a merino wool and nylon blend for a soft, non-irritating wear that won't lose its shape
  • Unique material is temperature regulating, odor-resistant, moisture-wicking, and entirely machine washable
  • Printed in one piece on a Shima Seiki knitting machine, producing less material waste and creating a seamless design that eliminates irritation
  • Comfortable, midweight waffle knit construction is excellent for layering or just throwing over a shirt
  • Articulated elbow offers optimal range of motion without restricting your body’s movements
  • Ribbed collar, hem, and cuffs add reinforcement to retain the sweater's shape
  • Carefully made with an exact attention to detail in China
  • 80% merino wool, 20% nylon
  • The 72-Hour Merino Crewneck has a slim fit that's true to size, take your normal size

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.
