Proof – now a Huckberry brand – always manages to make high-tech function and sleek style just come together. From their Nomad Shorts to their technical jackets, their entire line at least promises to reshape the way we think of clothing. Their 72-Hour Merino Collection is no less than any other.

They gave the 72-Hour Collection its name after testing the original Tee out in Iceland, where they wore it non-stop for 72 hours to prove its comfort and nature-resisting odor-resistance. The 72-Hour Merino Polo is just the natural successor to that one; a classy-but-casual cut from the same Merino fabric blend and designed for adventurous, on-the-go wear.

Proof Merino Wool Polo

Proof’s 72-Hour Merino Fabric is 89% 16.5-micron merino wool from New Zealand, blended with 11% nylon. This combo is the perfect amount of moisture-wicking, odor-resistance, and soft, lived-in comfort. It’s so comfortable – says Proof – that you’ll likely never want to take it off. At least for the first 72 hours. Nylon serves an additional purpose, beyond moisture-wicking; it allows you to machine-wash the shirt without losing its shape.

On top of all that, it’s reliably styled like any other trusty polo. The 72-Hour Collection also includes long-sleeve and short-sleeve henleys and the original Tee – all made with the same merino wool/nylon blend. Whether you’re rocking one of these shirts for 72 hours straight on your next adventure or just for chilling at a summer pool party, it’ll keep you comfortable, looking sharp, and smelling fresh.
