On an 18-day trip in the Colombian Amazon, our tester wanted several things from his shirt: It had to be light and packable, of course, and fast to dry, with good sun protection and big-trip durability. That’s a lot to ask from any garment, so it’s no surprise he was skeptical when he picked up the Featherweight. It’s so light you’d think it would shred on the first close encounter with a branch. But it delivered, on the Amazon and on many subsequent trips, thanks to nylon fabric that pairs a lower denier with a higher thread count, providing maximum strength for the weight.
Thru-hikers will swoon over the minimalist design—even the TPU buttons are thinner and lighter than standard plastic ones—but this shirt is not featureless. The zippered chest security pocket is large enough for a passport, and the flip-up collar provides good neck protection. Bonus: The antibacterial treatment kept the shirt funk-free for three days at a time. Fit is relaxed but not baggy.
