When you head out this camping season, do it in a way that will make your friends wish they were with you. Introducing the Modular Sleeping Bag System from the US Army! Save big on this ingenious system consisting of two mummy-style sleeping bags and a compression sack designed for travels when conditions range from mild to extreme cold weather! The modularity of this revolutionary design means that each individual bag is fully functional independently or they can be combined to suit your needs at any point during sleep time – so different combinations allow for various levels of warmth and control over air circulation. Either way, prepare to have some very jealous friends before long! This bundle consists of 3 basic components: 1 Sleeping Patrol Bag, 2 Intermediate Sleeping Bag, and 3 the Compression Sack. Reversible double-pull (opens end to end) slider allows top or bottom ventilation. Hood adjusts for heat retention; includes nylon drawcord and barrel lock. Some fading on the hood, refer to pics.
