US Gi Sleep system

[mrgoodfellow]

Newley aquired a brand new one of these, gave it a test last night only indoors lol so used the patrol bag and bivvy, was very suprised at how much room there was in there for a mummy bag, had a great sleep and look forward to using it outdoors in different combinations.

Any links to the product or pictures mate

It'll get smaller inside when you add the black bag, but the chances of needing all three put together are pretty slim, unless you like camping in really cold conditions. The green and bivy are suitable for most uses, and you can add a sleeping bag liner to give a bit more warmth.

Here's the link, these things are awesome!! I haven't used mine outside yet, only had it (the full system) a month and was so impressed with it, I bought a second bivy and green patrol bag for cheap to keep together so the full set can stay together. The bivy and green bag compressed to about the size of a basketball, and the weight is maybe 2kg?

Prices are all over the place, depends on new or used, but seen new upwards of $450, and I bought my lightly used one for $70 plus shipping from ebay.

yep thats the one i got, found it on ebay for under £100 brand new and sealed, apparently some of the ones on the market now are made under license and the bags are made in china which are slightly different a design, genuine ones have tennier labels on all three bags. Its a substancial bit of kit and im well pleased with the quality and comfort, as canadian mike says all three bags would only been needed in the coldest of situations i bought it for its combination flexibility.

Ya, with the Chinese knock-offs, the bivy isn't made of Goretex, it's made of some type of coated nylon, and doesn't breath. Mine all have the Tennier tags on them, and the Goretex stamps inside the bivy. Can't get over how soft the bivy feels, makes me want a GI Goretx jacket now!

Just be aware that that is a military survival rating , not a comfort rating and it requires a lot of additional insulation ....

"When combined, along with the Military Bivy Cover as an outermost layer, the 4 Part Modular Sleep System is designed for climates to -20 degrees Fahrenheit when the user is wearing a lightweight undershirt and drawers or mid‐weight shirt and drawers and standard cushion sole socks. The Sleep System will keep you warm to -30 degrees Fahrenheit when the user is also wearing a fleece jacket, like our USMC Military Issue Pullover Jacket, and soft shell or loft trousers. This system will keep you warm down to -50 degrees Fahrenheit when the user is also wearing additional layers of clothing, depending on the rating of the additional layers."

I think us Brits will be just fine. ;)
I'll have some experience by the end of the weekend on what is required at a 0 degree temp. (all or just black). "Looking" at the bags, I'd say you'd still need the full system and not just the black, but we'll see.

had another very comfy night in just the cold weather bad alone, and my house isnt exactly warm in the bedrooms as i rarely put the central heating on, again suprised at how much room i had to move around and turn over, Ok im not oversized at 6ft and 40inch chest but still i was very impressed with the dimensions of the bag which is the smallest of the bags and didnt feel mummified as i have in some other bags.

Just a point, Lads & Lasses, I bought one of these systems pre-loved from a milsurp place in Texas and am quite happy with the set-up.
Quite heavy for the whole kit and a little large even with the compression sack. The sleeping bags are NOT over long though, particularly the black intermediate
bag which was a tight fit for length - I am 6'4"- and I tend to use it as a blanket where it is still cozy warm.
There are EXTRA LONG versions available if you hunt them out. Got one new in a bag from Ebay in the US for about 60 USD and am delighted with the extra 6" or so in length.
I have also read somewhere that the US armed forces state that after 20 washes or so the bag should be discarded as the insulation is a bit raggedy at that point and will not be effective. My patrol bag (that's the green lightweight one) did seem a bit a little that way as there's less fill in it anyway. A night in front of the telly pulling at the loft through the covers fluffed it up nicely though!

The MSS, or Modular Sleep System, is no longer used by the US military, but when my brother was serving in the USMC some years back, he was issued one. Nowadays, a full complete (and authentic) MSS can cost several hundred $$$$. I picked up a bivy back when they were $40 on the Amazonian...now they're pushing $60. I never used it because it was just so darned heavy and bulky for what it is...2 lb 3 oz/nearly 1 kg. My DD tarp weighs less, for crying out loud! That said, the green Patrol Bag is probably the better part of the whole system in terms of weight-to-warmth ratio. It's a decent 3 season bag from what I've heard, and you can squeak it down to 0 C with a decent pad or mat. Otherwise, 4 C is probably a more accurate comfort rating. Keep in mind that the US military's ratings are based on "survival" temp, that is to say, the lowest temperature rating before you start to suffer from the cold...in other words, at that temperature, you will be uncomfortably cold. The Patrol bag weighs in at 2 lb 5 oz, or just over 1 kg. And for a synthetic bag, it compresses well.
The black Intermediate bag weighs 4 lbs 6 oz, or nearly 2 kg. The whole system (excluding the compression sack) is almost 9 lbs/ 4 kg - it's quite hefty and takes up A LOT of room...the stuff sack itself is large enough to be a rucksack: 14x30 inches, or 36x76 cm. Not a decent choice for backpacking IMO, especially since there are better weight-to-warmth ratio options out there, and many for less cost. Still, the Patrol Bag offers the best overall value, I think. Looking at Evilbay right now, it costs around £15.
