Our best-selling everyday polo—built from anti-odor merino wool for your most demanding adventures
We call it the 72-Hour Merino Collection because every piece is built with the comfort, durability, and odor-resistance to last three days of nonstop wear. Its superpowers come from Merino wool, an ultra-soft and high-performing material that turns any piece of apparel into the perfect travel garment. But you don't have to wait for your next trip to the Utah backcountry or the Amalfi coast to reach for the 72-Hour Polo, because it's just as well-equipped for our daily demands—think strolls through the park, at-home garden build-outs, wrangling kids in the backyard, and more. It’s the only polo built to fit every bill.
