U.S. Military MSS (Modular Sleep System)

I bought the MSS Sleep System from Smith's Surplus and it's brilliantly adaptable for any environment. Made with high-quality materials, it's durable, and features a waterproof layer that blocks wind and water. With two sleeping bags of different sizes, it caters to different weather conditions, keeping you toasty even below freezing. Its versatile, modular design makes it a cost-effective and practical choice. I bought the MSS Sleep System at Smith’s Surplus and I have to tell you, it's the only… Full review

Wiggy's Super Light FTRSS

Good all around bags. Combined they're incredible. Easy to clean, pack, great kit. Being retired Military, I have used some incredibly crappy sleep systems.  Frankly, so bad it bordered on criminal to issue them to the troops.  But that's what we get. I discovered Wiggy's oddly enough by the boots he made. Lamilite insulated leather boots that were freaking amazing.  So I figured if those worked, well.................. I invested in the FTRSS system in the boat foot style bags. I've never looked… Full review

U.S. Military MSS (Modular Sleep System) Patrol

I have the Patrol bag from the MSS. Nice outer bag with top grade mil spec materials. Grabbed it on sale for $50 CAD. Have seen the system with Bivy bag and Intermediate bag for reasonable dollars. Looking forward to some early fall deer hunting camp. Always understood that military specifications were standards that were rigorous and that gear approved for our nation's forces was made to hold up to hard use and give years of service. Good enough for the military, then that is good enough for me. Full review

Mountain Warehouse Everest Down Sleeping Bag

A good bag for what it says, lofts well, very warm. To Jo Bets, the bag is rated -11° comfort and -19° limit. If you use it at -3° you will sweat, fabrics are only so breathable. I have used it at -13° and found no problems. Get yourself a bag to suit warmer temps, say 2° comfort and -7° limit. I previously had one of their Everest models and 15 years on it's still usable. All in I've been outdooring for over 40 years. For the money it's good. Full review

I slept in this bag for four months in the Arctic and slept like a baby. Full review

Western Mountaineering Puma Super MF

Super WARM and very light... I have used this bag down to -15° and have been completely warm and comfortable. I have no doubt it would be OK even down to -25°, and I am a VERY cold sleeper. I usually need a bag that is rated at least 20 deg warmer than claimed, but not with this bag. When it is not too windy I often just sleep in an open lean-to or under a tarp, and am just fine in the middle of winter. The MF shell offers excellent wind and water resistance, zipper works great, there is plenty… Full review

Western Mountaineering Puma GWS

The Puma GWS lives up to the ratings and is high quality. The zipper works flawlessly and the cinch cord is easy to use. I slept out in -5 degrees with 25mph winds in a single person tent, warm all over. Remember a sleeping bag is only as good as its sleeping pad. In the winter you will get cold with any sleeping bag if you use a cheap sleeping pad. Full review
