The highest performance merino tee on the market is also the softest

It's called the 72-Hour Merino Tee because it has the comfort, durability, and odor-resistance to last three days of nonstop wear. To put it to the test, every year Proof grabs their backpacks and takes off on another epic adventure wearing only one t-shirt all weekend long, making sure it still reigns supreme as the best travel tee out there. This time Ben and Alex headed to southern Utah and met up with Rashad and Ron Frazier, brothers and owners of guided adventure company Camp Yoshi. Led by adventure expert and filmmaker Sinuhe Xavier, they all roamed the desert for three days in their 72-Hour Merino Tees. Spoiler alert: the tees kicked ass—watch for yourself in our latest edition of the 72-Hour series below. Now the question is, where will you take yours?


  • Premium tee with a stylish cut that combines comfort with technical performance
  • Engineered fabric harnesses the incredible natural properties of merino wool to wick moisture, resist odors, and regulate temperature
  • Nylon reinforcement allows the merino fabric to be machine washed while retaining its shape for easy care throughout the life of the garment
  • Made in Indonesia with 16.5 micron wool sourced from New Zealand

I wore this to Seattle and back and then up to Maine. Zero odor and still looked fresh.
