Gear Review: Kombi Bamboo 4-Way Stretch 1/4 Zip-Neck

A lightweight layering piece make of bamboo

The silky feel of the Kombi Bamboo 4-Way Stretch ¼ Zip-Neck makes it a primo layering piece, since it slides easily beneath a fleece or jacket. “And it stretches like crazy for fantastic freedom of movement,” said one user.

After reaching the top of Colorado’s 10,839-foot Hahns Peak on a 5°F day with blustery winds, she didn’t get chilled, thanks to the bamboo’s natural moisture management. Best of all: no stink, even after four days’ wear. $50-55; 8 oz. (w’s S);
