These CPGear grenade pouches are intended to hold M67 (C13 in Canadian service) fragmentation grenades but are likely to fit other grenade types as well. One of the photos shows an M26 frag grenade in the pouch, indicating its versatility for different grenade sizes. The pouches are in good condition and come in Cadpat camouflage. There might be a few variations, and you will receive a random pouch from the ones shown.
