I own both the old school ECW military bag and the new Modular issue bag and have alot of field experience with both. I go over my personal experience and 2 cents when comparing the "old school" goose down filled ECW military sleeping bag VS. the new issue ECW modular system. The second half of the vid shows how to make a DIY TYVEK bivy for any sleeping bag.
