The 100% Light Merino Pocket T-Shirt is a lightweight pocket tee from Japan’s Yamatomichi. Because it’s made from merino wool, not only does it regulate temperature really well, but it’s odour resistant too—making it particularly good for long hikes where you’re going to be away from a washing machine for a while. As with everything from Yamatomichi, a lot of thought has gone into the shape too—and that wide, boxy fit makes it a lot more wearable than the more fitted merino base-layers around.
