Couldn't have her getting cold. But hey the getting out is pretty quick. Really easy to undo all bags at once. **Q: What are the specs a backpacker would want to know, like each piece's weight /total weight? Compressed size/dimensions?** A: Hi Dave, I measured the pack for you and it is 22 inches long by 14 inches wide in the compressed sack. The total weight is just about 8 pounds and I cannot stress enough that this system is one of the warmest you can buy and will protect you in the coldest environments. **Q: How waterproof is the gortex bivy cover?** A: One morning I woke up in my hammock, sleeping in my intermediate bag and this goretex cover, and much to my surprise there was FOUR INCHES of water in my hammock but I was bone dry in the bivy. Yessir, it is w a t e r p r o o f. Don't spray anything on it. **Q: hi, i am 6' 6". how long is this bag and will i fit in it, covered and confortable? tnx for info!** A: I am 6'6" also, ordered the system for my 11 year old daughter, it kept her warm in a non heated shelter @ - 15 F . The only part of the system that works for me is the green 30 degree bag if you can find one in a long it is a great warm weather bag. I have three green bags, one fits well. All a great deal. ## Frequently Bought Together - Military Modular Sleep System 4 Piece with Goretex Bivy Cover and Carry Sack - USGI Industries Military Style Poncho Multi Use Rip Stop Camouflage Rain Poncho - Therm-a-Rest Z Lite Original Camping and Backpacking Sleeping Pad --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/1603400-military-modular-sleep-system-4-piece-with-goretex-bivy-cover](https://www.desertcart.sg/products/1603400-military-modular-sleep-system-4-piece-with-goretex-bivy-cover) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-09-29*
