A crampon pouch is not exactly rocket science but OR puts some nice touches on theirs. There are two drain grommets on the bottom, the dual-action zipper opens the pouch halfway and there are twin daisy chains sewn into the back and a small cord loop on top for easy attachment to your pack.
It’s plenty durable with Hypalon end caps to ward off the frontpoints. The piping on the edges is even reflective, all the better to see it with in the dark. There’s even a handy little zippered pocket for extra parts and such. Light too at 3.8oz; I likey.
