First off, this bag is rugged!!!! Note, be very gentle and careful w the mosquito net, as you would any. But I used this bag to sleep in the Philippines jungles in a hammock on a mission trip for 3 weeks. Lots of bugs, but not on me, bag was great. I also use this regularly at our cabin in Washington where weather can get down to 30 degrees, and this bag is no problem, just add a Sea to Summit Reactor Extreme +25 degree sleeping bag liner! Just an old foam USArmy ground roll under. I also have used this bag on the Pacific Crest trail w a Reactor Extreme and a good Foam ground roll in 32 degree weather. This bag is great if you know how to do modular layering which we learned in the army w our modular bags. The bag packs down so tiny, you can add a tiny reactor liner and ground pad no problem. This bag becomes a four season bag. Also, unlike I have experienced in the past w my 15 degree expensive mummy bags, when you go modular, you aren’t stuck sweating in a 15 degree bag in 40 degree weather, and thus freezing because while asleep you climb out of the bag while too hot, then freeze because then it is cold!!! Instead you just subtract the reactor liner if too hot. Or add it if you know will be cool. The mosquito net is priceless as it allows you to just bring a good tarp or lightweight fly tarp instead of full tent. The ripstop fabric on this tent I have taken everywhere the last 3-4 years still looks like new. It is bulletproof tough. If you want a modular system this is the way to go. ***update, I am testing this bag in my backyard along the Delta, temp is 33 degrees, I have just the following: Snugpak Jungle Bag, Reactor Extreme Liner, wool socks, medium weight thermal top/bottom underwear. No gloves no hat. It is comfortable but this is the limit. I am 5’9” I find I have the mosquito net above my head about 5”. The I just breath not directly out so as not to suck in cold air. If I added gloves and pants and another top over my underwear I would easily be comfortable at 30 degrees But I do think 30 is the limit w extra clothethes. The ultimate setup would be this jungle bag w a Reactor Extreme and a bivy bag to just roll it all up and throw it down quickly. Especially a MSS bag. W a bivy into the 30’s no problem! Note the key to all is a heat liner like the Reactor Extreme or Snugpak fleece liner. I keep my liner in my bag, roll it all up together, goes in the tiny stuff sack, and just a great ultralight thru hike kit w a mosquito net! Can’t beat that!!!! ****UPDATE**** This bag now a 4 season bag for me as I have started using it like a US Army MSS layering system!! I used this 36 degree Jungle Bag as an outer layer with my 30 degree US Army MSS Patrol Bag (bought used on Amazon for $30) in the Sierra Nevada’s hiking near Yosemite in January. Temp’s got down to 5 degrees I was toasty warm! The US Army 30 deg patrol bag fits like a glove inside the jungle bag! I then had the MSS Bivy as my only shelter over that. I might have been fine even if it went down to zero degrees. I was only wearing t shirt, socks and boxers. The cool thing about this is that the jungle bag, seems big enough to be the outer bag for most medium to light sleeping bags, thus providing the mosquito netting as coverage for all!!!! The advantage to this layering system is you can avoid having to lug around one giant bulky 0 degree bag. Instead you can have both small rolled bags separate in your pack for streamlining or you can roll them together w a bivy like the MSS system and attach the big roll to outside of your pack. Very versatile! This jungle bag when used this way becomes an easy bug net for all your sleeping bags. Read more
I cannot over stress how small it is seriously have fun finding anything smaller. I needed a sleeping bag for right above freezing temps that was small I really had an issue finding anything this small it says it’s a 45f sleeping bag which yeah I find that accurate but I put in a sleeping bag liner to add to the warmth and with my pad under it’s comfortable at freezing point and with my down sleepers pants and jacket with my base layer clothes and a quality beanie I have zero issues sleeping in 25f with personal expirence pretty sure it can get colder and comfortable still. The nice thing as well is I can unzip the toe box unzip the bug net and zip down the main zipper and spin it around to use essentially as a quilt and sleep on my side while staying warm and comfy. To me this is now my go to lightweight small sleeping bag I use 3 seasons. I have zero idea why ultralight guys don’t even mention this sleeping bag. Also great if needing to travel around like to a friends house, hostels etc you EASILY put it on your carry on for planes and it takes up as much room as 4 smart water bottles roughly and with a small liner that’s about the size of your fist if you wear a size large gloves yeah this is comfy small and easy to take with you may it be on a trail or a few thousand miles away from home Read more
I took off one star for the (unduly) high price ... Pros: Light-weight, compact , OD-green, built-in SKEETER NET !! Cons: Unduly high price premium ... really the only "con". Note: Available in Right or Left-handed zipper. I really do love everything except the price, on this bag. Since I live in Texas, where the winter temps (including wind-chill) very rarely (almost never) get down to zero-farenheit ... I decided to build my OWN (customized) version of the USGI (bivy based) ECWS sleep system (which is designed to go down to ~ -50F). In doing so, I can save on weight and money and (also) get INTEGRAL BUG PROTECTION !! So ... I went with a MILSPEC GoreTex Digital ACU outer Bivy bag .. (@ $110+ship)and this Jungle-bag, as the two, primary components ... ... Aditionally, I have purchased a compact ~20deg-F synthetic mummy-bag ($28 @ Amazon) ... an Adventure Medical Thermo-2 (aka SOL) vented thermo-bivy and a Magellan fleece liner (both items are very compact and feather-lite) ... just to increase layers and reflective insulation, during RARE cold-snaps or a really bad winter (happens once or twice each decade, here, in Central Texas). So ... I have not weighed the total Texas-ECWS system but it is clearly much lighter than the MilSpec system ... The cost ? ... hmmm ... $110(Bivy)+$28(cold-bag)+~$70+(Jungle-bag)~$28(Thermo-Bivy)+~$16 (fleece liner)+ ... equals ... (cha-ching!) ... under ~$275 (including shipping) ... ... Ok ... so maybe I dint save much (or any ... if "used" on eBay).. ... BUT ... I can nest all this up inside the Bivy and wrap the whole thing in my two ACU ponchos ($50 per pair) and it all makes for a very light and compact package which can shelter me in freezing rain and raging gales, in the worst cases ... OOPS ... I also got a Thermarest reflective foam pad, for ~$20 ... might even add a second (used) miiitary sleep pad, for another $10 .. I'm old and the one pad ain't quite thick enough. Anyway ... this Jungle-bag, in conjunction with the MilSpec Bivy, are the core of this system and these two components are the most expensive parts ... at $110 for (new ACU)bivy and $70 for the Jungle bag. PS ... SnugPak sells the very same compact bag, minus the mosquito-net, for something like $30 less !! ? ... So ... I paid a ~ $30 premium just for the integral bug-net ... Worth it for the convenience of integration but ... REALLY !!! THIRTY DOLLARS MORE !?? Love it ... (bottom line) ... They can charge this much because nobody else provides a comparable solution (except, I think, is it SlumberJack? that makes a bivy with a built-in net ... same idea ... sort of). Not really any cheaper and not as "tacti-cool" as what I finally got. Plus, on hotter nites, u can use the bag, alone ... with just a pad. ... The square bottom unzips all the way and can be used as a blanket and you can also sleep on top of it, to increase your pad-loft, if the bugs are not too bad. Lots of options and useful qualities and features ... good build. Read more
