72-Hour Merino UPF Quarter Zip

Story

A travel layer spun in magical merino wool

We call it the "72-Hour Collection" because every piece is built with the comfort, durability, and odor-resistance to last three days of nonstop wear. Even more, the incredibly soft merino wool is infused with the strength of nylon to ensure it never shrinks in the wash. Just a little heavier than your average t-shirt, you can use the UPF Quarter Zip for sun protection in warm weather or as an extra layer when the mercury drops.

Features

• Merino wool wicks moisture, resists odors, and regulates temperature
• Rated UPF 50+ for sun protection
• Lightweight design is just a little thicker than a regular t-shirt
• Nylon reinforcement allows the merino fabric to retaining its shape
• Thumb loops keep the sleeves in place
• Slight curved hem adds a refined, stylish touch

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.
