The small sack it comes in is slightly oversized, which allows you to keep additional survival items in it. I was able to fit 20' of 550 cord, one of Doug Ritter's AMK Pocket Survival Pack, Doug Ritter Special Edition eQ Hands-Free Multi-Light , 10 Katadyn Micropur water purification tablets and 6 Gerber Breast Milk bags. This setup was a little bigger then I would like to carry in my pocket, but it makes an almost idea survival kit for backpacking or in a Camelbak for day hikes.

For some reason the whole review would not post in a single post. I have no idea why, but sorry for the multiple posts.
