72-Hour Merino Polo Shirt

Story

Merino wool performance polo shirt for men that never itches and stays fresh for miles

For adventures that call for packing light and minimizing laundry days, our bestselling 72-Hour Merino Polo shirt is overqualified for the job. It’s spun from merino wool with a nylon core for comfort that’ll last. Even after 72+ hours of constant wear, it’ll still pass the smell test thanks to its naturally odor-resistant and moisture-wicking properties.

• Cut with thermoregulating, odor-resistant, moisture-wicking Australian merino wool
• Three-button placket at neck with low-profile snaps in a matte black finish
• Free collar rests around the neck and retains shape
• 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 for easy care throughout the life of the garment—just stick with cold/gentle washing to avoid shrinking
• Rated UPF 30+ for sun protection

Sizing

• The 72-Hour Merino Polo has a classic fit, take your normal t-shirt size
• Wool-based products will shrink slightly in a conventional washer and dryer, so we recommend either cold/gentle washing and air drying, or taking the next size up to compensate
