To make carrying your outdoor odds and ends that much easier, we’ve grabbed this square clip-on accessory bag from our friends at Topo Designs. It’s made from a durable mix of 1000D and 420D nylon pack cloth, with a rugged zipper pull and a heavy-duty aluminum clip. Whether you’re out on the trail or just need a place to toss your keys on the way to work, this thing will serve you well.
