Proof’s 72-Hour collection is built for guys on the move. The line—one of Huckberry's most popular in-house labels—leans into the power of merino wool, delivering lightweight layers that regulate temperature, resist odor, and stay wrinkle-free for, you guessed it, a full three days, at least. The tees, hoodies, polos, and pants look sharp and feel even better—no matter how long your layover or how packed your weekend adventure gets.

To prove it, Huckberry created the 72-Hour Challenge—sending guys into the wild to wear the gear nonstop for three days of hiking, climbing, and exploring. Call it R&D that's a lot more fun than the standard durability testing. The takeaway? These pieces really can go the distance. Whether you're packing light for travel or just want to simplify your morning routine, this is performance gear that doesn't look like it. Even better, right now if you buy any two items from the 72-Hour Collection you can score 15% off. Now that's a smart move.
