Great system, super durable but for civilian use I would say there are better options. The technology is just old so the system weighs a ton. The green patrol bag is supposed to go down to 32F, but even wearing my entire ACU, insulated boots, level 3 fleece, and goretex tops and bottoms, I'm only barely comfortable at 40F. Granted we don't usually use the sleeping pad but still

I bring plastic bags from the shoppette or any store so that when my boots get muddy i can stick them in the bags and stick those into my sleep system to keep them warm for the morning without getting my stuff sack or sleep system dirty. It also does a good job of keeping bugs out of my boots as well.

Good report. Try inverting the storage bag if you plan to stick muddy boots, etc inside. Then, you don’t dirty up your sleep system when it goes back inside. Really like your arched insert to keep bivvy fabric off your face.

Excellent video, thank you. Just picked up a mint system for $95. Back when I was in all we were issued were the extreme cold weather bags. They were ok but had their limitations..

Tested mine in the feild -5 Fahrenheit snow winter campout got used works great

That was a Fun video, best bang for your buck, I've slept in mine comfortably with a piece of reflectix as a sleep pad in -35 C with 40 kmh winds in a snow storm.

My son is in the army (12) years now. The acu bags are known to leak. He went thru 3 before he got one that was good.

Outstanding video. This is absolutely the Best Review of the MSS. Thank you for all of the tips and advice. Much appreciated.

I think you really know your stuff, very impressed with this video! I have an MSS bivy like yours, really like it for cold temps and wet conditions in Ontario, Canada. Looking forward to more videos!

*Boot liners* are the best investment you can make in staying warm in the field

TIP/TRICK = I wear Buff Headgear around my neck/head/face before crawling into my sleeping bag which is inside the Gore-Tex Bivy. Buy keeping my head, brain & neck @98.6º, my body will continue to circulate warm blood to my extremities. I've read all the replies to date & added my comment to several. HOT HANDS for hands or feet goes a long way to keeping those extremities comfy warm anytime, anyplace. I only have the outer Gore-Tex bivy. I put my Eddie Bauer Kara Korum Mummy Down Filled sleeping bag inside to keep it dry. I have & use the Military Thermarest mattress to keep me insulated from the cold ground. I've used this equipment inside tarp & tent shelters. Any & all sleeping bags will keep the person inside warmer & drier their inside a Military Gore-Tex bivy. I've "subscribed" & rang the notification bell.

Sound advise. I have the woodland camo.

I got a good one and I coated it right away with gortex spray but the bag is so good that the spray just beaded all over. Hand to wipe many hand into the puddles to smear it all over. Best piece of kit ever

If you want to make a acu bag actually camoflaged I recommend eather spray painting a small amount of od green on the bivy or making a 4th layer that's hunting bind camo material doing this allows you to stelth camp on a budget or just get rid of the annoying acu color

If you get down to your silkies, you’ll be surprised how much warmer you are. The bag is able to insulate way more of your body heat with is the real secret to a sleeping bag.

Great Tips and review. Just got Back from a camping trip. First time I really got test my system. I was impressed. I used the Green Patrol and the Black intermediate bags together without the bivy while sleeping inside my USMC Combat 2 man tent. I think at night it got down to the 40's and I was snug and warm in my pajamas and socks. Awsome system. Only small Cons for me is its more restrictive tham my Coleman Big Basin Bag. But not terrible. MMSS is more of a mummy bag. Also I noticed that the velcro that secures the zippers will snag the material on the bags. Especially when you put the bags in the Washer. I guess you just have to be careful and kerp the velro fastened prevent snags. Wondering if you or others have noticed the same problem with snags. Other than that I love the system. I'm 5ft 9inches 250+ and I feel lenght wise the bag is about perfect for me. I think taller people may find it a little short or need to bend their knees some inside. I'm a bigger guy but once inside and situated I dont feel to constricted or clostriphobic. Also for extra warmth I'll throw my Military "Woobie" blanket inside also. Mine is Woodland Camo and seemed to be in new/unused condition $109 Shipped on Ebay

I was wondering when you were going to actually use a sample MSS for the vid. I didn't see it until you pointed it out

Thank you so much for this. Very informative.

Great vid Good to see an up to date review on these Sleep Sytems.I own the Digital Cam set up.keep them coming.i subscribed🌲

Important is ! That everything is like outside, totally waterproof !!!

Mylar blanket for the wind. It is light and will reflect heat back to you.

I have one love it! Just wish I could get it with a left hand zipper. Nice review!

Put hand warmers in it . They well keep you warm on cold nights .

What is that plastic peice you used?

maybe a stupid question... how well does the mss or uca bivy cover work with other bags? Im thinking of picking up a kelty tuck -20 bag and fitting the bivy cover over it.

Gortex will leak after a while in the rain. Eventually it absorbs water I used to have a gortex jacket that would eventually get soaked even when treated with a repellent. Water would bead up at first but after several hours in the rain would start getting damp. I used fleece liners or field jacket liners but they would start getting damp to. Gortex dries fast. I never sleeper out in the rain in the Gortex bivy was always in a truck cab or in a tent, or on a GI cot with poncho spread out over the top. Can't go wrong with the poncho. And wear polypropylene long johns in extreme cold.

I just got one today for 50 bucks mint condition nice system

I use All free and clear in a new kitchen waste container and hang it outside for a few hours and then put it in the dryer on fluff with no heat for a short time

If the tape on the seems comes off use a heat gun to put it back. I've done and it works well.

I love my mmss... has saved my ass on some COOOOOOLD nights!!

Very good, Thank you very much

Good one! Thanks man!

They do make an extra long version for taller people.

3:55 though 😂😂😂

what size in packed condition?

So I got one of these from my Dad, and wanted to take it backpacking. On the intermediate cold bag it says it can go down to zero, is that by itself, or is that in combo with the other two?

fill a nalgene bottle with hot water and throw that in the bottom of the bag, it will help keep your toes nice and toasty. Might as well throw that pee bottle in the bottom on the bag too!(definitely ganna keep the pee bottle in mind) (just don't go and accidentally drink from it)

Army Navy store near me (Upstate NY) = ~ $180

don't store it compressed? so just keep it in a big loose pile?

Thank you! I'm an idiot: I reversed the patrol and intermediate bags. No wonder the buttons never lined up!

Use a woobie for extra protection in very cold weather

Btw the acu pattern works well for turkeys and deer hunting too lol !

The plastic insert you use to 'elevate' the inside of the bivy: where did get that piece? Length?

For backpacking purposes and you know the conditions are say 40F and clear skies, would you recommend just using the intermediate bag to reduce weight?

I strongly believe is not call ACU if I’m not mistaking is call UPC

I just back from a field exercise and it was 26 degrees. I used my entire sleep system and everyone out there froze their feet. It was terrible

Thank you for the useful tips!

The best way to find out what you really need is just get out and do.

Do these come in variable sizes? If so what is the largest size?

i dont even see the bag.... unbelievable.

Nice video, can you clarify what you meant by reviving the gortex? I always thought that once it start to leak, you have to patch or seam seal that section. Otherwise, you're going to have a leaky bivy. Thx!

Funny comment in the video about the amazing camo.

Hi! How to use poncho liner with this IMSS system?

Putin loves UCP camo.

xcool friend !!! 1 A

I always sleep in tents tarps and hammocks with tarps....ditch the bivy and add a poncho liner

I beg to differ I think the ACU Camo sucks, it only works in rock quarries.

all good except the foil blanket, they are trash and will just make you wet in your bag

Negative 20? I don't think so

I am retired Army I own one but I am looking for another

All the worst camo ever comments 🤣🤣🤣 98% all sleep in a tent anyway, that camo sure comes in handy in that tent!

i can see it that camo is crap

62000 people are a little smarter …

Worst camo ever!
