April 13, 2013 Hello Fellow Nikon Cafe members: I was wondering if any members of Nikon Cafe have used the US Military's ACU modular sleeping bag system, and what your comments and thoughts are about these sleeping bags. I'm curious if they are of good quality and if they are warm. I would appreciate any and all comments if you have used them or know about these sleeping bags, and I want to thank you for your help. Comments both positive and negative would be appreciated. Thanks again.
