    Sleep comfortably on your stomach and side.

    Sierra Designs took a new approach to designing the Backcountry Bed 600 Sleeping Bag so you can sleep comfortably at the car-camping site. Free from extraneous hardware like bulky zippers and drawcords, this intuitive bag features an oval-shaped opening with an integrated comforter that helps the bag adapt to variable temperatures. You can tuck the comforter's sides snugly beneath you and stay warm in temps as low as 15°F, or you can pull the comforter out to stay comfortable during the warmer parts of the year. Its unique mummy design allows you to sleep on your stomach or sides as well as your back, which is excellent because most mummy bags only let you sleep comfortably on your back. Sierra Designs stuffed this bag with 600-fill duck down insulation that was treated with DriDown, which means the down won't just absorb water and get cold and clumpy if it happens to get wet.

    Sierra Designs built the Backcountry Bed's shell out of ripstop for durability and the liner out of taffeta for your comfort. This bag also features insulated pockets for your arms so you never wake up in the middle of the night because your hand slipped out of the bag and is slowly chilling. There's also an integrated sleeve for your sleeping pad so you never roll off of it during the night and wake up on the rocky ground. This bag is warm enough for the cold nights, versatile enough for the warm nights, and comfortable enough to keep you nice and cozy on car camping trips.

    • Familiarity: I've put it through the wringer

    I owned a synthetic mummy style sleeping bag before this and decided to upgrade to a down sleeping bag and this bag seemed to look fairly comfortable. It didnt have many reviews when I first bought it and still doesnt have too many so i decided to leave one. FIrst, I am a pretty warm sleeper and live in the southeast where temps rarely drop past the teens unless you hit the mountains. The coldest i have taken this bag out was in the 20's and i was comfortable and warm. I will often lay in with a light base layer and end up shedding them everytime in the middle of the night. I absolutely love this sleeping bag and will, more than likely, never switch back to a mummy. Ive even used this bag in the low 60's and have left the comforter off and was comfortable and not too warm. The only really negative thing about this sleeping bag is you can't really bend your knees and sit up while laying in the bag. That's a small issue and definitely isn't a deal breaker. Im 6'0 170lbs and bought the long and it is great.

    Too comfy for the backcountry

    • Familiarity: I've used it several times

    Sierra Designs please hire me I may have just sold 15 of these. But actually I just spent a week paddling in the Maine and didn't know people could be this comfortable camping. I had almost everyone in my group crawl in my tent to try this thing out. I'm usually a stomach sleeper and could not be happier. Wake up in the middle of the night cause of a spooky sound or full bladder? Not a problem. Drybag fails you and the outside it the bag is wet? Not a problem. Friends start asking you to borrow your gear? A problem. This thing also packs like a clown car. A big problem with mummy bags I have is a cold face but this lets you wrap up tight without feeling claustrophobic. It's the ultimate climate control machine with the hand sleeves, foot access and zipperless design. I can truly say I wasn't looking forward to a night in my own bed cause this thing was so amazing.

    Best nights sleep ever

    • Familiarity: I've used it several times

    I picked one of these up after being a little let down with my TNF synthetic 20 degree bag. I think one of the best way to make a good trip a great one is getting a good night's sleep.

    I am a very active side sleeper and I have never had a good nights sleep in a sleeping bag. Until now. This was easily the best sleeping bag I have ever slept in. Easy to move, no twisting, comforter portion stayed put.

    Temp was around 40 and I was comfortable in a t-shirt and boxers. Great bag, highly recommended. Not sure I would go to the limit of 15 but it should be good at 30 or above.

    Great alternative to a mummy

    • Familiarity: I've used it several times

    Seems like one of people's biggest concerns with this bag is the need for a pad underneath to stay warm. Understand that this isn't a downfall of this bag. Even if there were down on the bottom side, it would be compressed when you lay on it and provide no insulation. Down only works when it maintains it's loft. If you're willing to use this bag the way it was intended, you won't be disappointed. You may actually have to get used to sleeping comfortable and unrestricted inside a tent or under the stars. It is a little weird. I appreciate being able to put my feet out the bottom when I want. I stayed warm in Utah in September under the stars with this bag (and to be fair, I wasn't using an insulated pad then either).

    Excellent design

    • Familiarity: I've used it once or twice and have initial impressions

    I love the idea of this sleep system. With my sleeping pad in the sleeve, the bed stays comfortable and sturdy, but I can still change positions throughout the night. The foot vent works really well, I love not having to unzip the bag to let my feet out. A bit more room at the hips wouldn't go amiss. I'm thinking about reinforcing the seams where the quilt meets the bag, as I feel like I might tear it out over time while getting in and out of the bag. You kind of have to scoot out to get your legs out, and it puts pressure on those seams. Overall, very happy with this bag!

    Still a bit confining...

    • Familiarity: I've used it several times

    I love the quilt top - it is nice and snuggly. Love the arm pockets too. Super soft feel all around and very light, but not such an important selling point since I am car camping and weight isn't an issue. Foot vent is a nice feature but only works when you are on your back as it requires you to bend your knees toward you to slide your feet in and out. If you are on your stomach, it is physically impossible because your knees would have to bend in the opposite direction to access the flap. You can only "crawl" up the bag and then slide back down to try to access the vent flap.Because of the leg taper and the fact that the opening hits me at the hips, I had a hard time moving my legs into a comfortable position when on my back. I can't sleep well with my legs straight out. I tend to make a figure 4 and that just pulled the fabric super tight.

    The bag was too warm for the 50 degree weather when I used it first and although there is a foot vent, it doesn't provide adequate ventilation for my legs. I got uncomfortably warm in the upper leg and waist area even with my feet out of the vent and the quilt lowered. Since the opening is so high up, as mentioned before, you can't easily hang a leg out to get venting. You have to scoot up to the top of the bag, hang a leg out and then try to cover your upper torso with the quilt. It didn't really work out great cause now you are half way up the bag.

    Couple of design mods I would love to see on this bag that would make me a true believer: 1. cut it wider in the hip section, particularly on the ladies bag 2. figure out a side baffle for ventilation 3. cut the hole lower down in the bag 4. for the car camper, offer a bigger bag all around, kind of like the big agnes concept, but better because of the quilt feature.

    All-in-all, I am still deciding if this is a keeper or not. I am considering dumping bags in general and going with a quilt. Had to give this a try first, though. Love the concept, but not so sure about the results.

    I have one. It's a 15 degree bag, which is plastered all over this site and on the manufacturer's site and on the bag itself. You can't blame the bag for being too warm for the conditions. That just means you're using it wrong.

    I'm 5'10", 185# -- should I get the regular or long? I've read elsewhere the bag runs a little short and the regular would feel cramped at my height despite being advertised up to 6'.

    Hey Michael,

    Depends on if you like your sleeping bag to be tight or not. If you do not need much room to move around, the regular should be fine. I prefer this because the bag is warmer the tighter it fits around your body. The tall may be a bit baggy but you could probably make it work. For your height and weight I'd imagine the regular would be perfect.

    Hey Daryl, thanks for the answer!

    The other one that I'm looking at is the Nemo Equipment ones - love the "spoon" style ones since that also fits my sleeping style. Just wish Nemo bag had the ability to stick your feet out.

    I've been in the Backcountry Bed in the store but the thing that bugged me about it was that it didn't seem like the quilt would stay in place/tucked in during the night (especially on my back and that it would be all pulled forward to my front).

    Did you have any issues with drafts getting into the bag or the quilt staying in place during the night?

    Best Answer

    No problem!

    There's no draft in the foot area, there's quite a bit of overlap so that was fine.

    As for the blanket part, if you're quite active in you're sleep I could see it coming untucked, but I'm pretty good at shutting off for the night so I haven't had any issues there either. I also barely fill the bag at 5'5'' 150#, so there's enough blanket to keep me warm.

    Just a follow up for the customers. After using this sack about a dozen times now, i have a little further insight.

    At first I wasn't using the sleeve for my pad (the pad was too big), but recently picked up a Thermarest which fit perfectly. If I had to nit pick, I would say a draft could happen without the pad if you move around a bit in your sleep, because it was definitely a little difficult to get a good tuck with the blanket.

    However, using the sleeping pad adds quite a bit of structure to the system and it's much easier to get a nice tight seal. I actually caught my self a little too warm the past two nights of camping and had to opt to an untucked blanket.

    Has anybody actually used this on a trip?...

    Has anybody actually used this on a trip?

    I see a lot of questions and videos about how awesome this bag is.

    I love the features on this (if there are any other sleeping bags where I can stick my feet out, let me know!)

    But what I really want to know...has anybody actually USED it out on the trail?

    Also, I was told that you HAVE to have a sleeping pad with this one as the other mummy bags you may not have to have a sleeping pad, but this one definitely requires one for sleeping out on the trail.

    Hey Allison,

    I've used this out on the trail last weekend and plan on hitting Moab this current weekend with it. Like mentioned in several comments below, you will need sleeping pad unless your sleeping on the beach in the middle of summer. Without one your back will essentially be on the ground since theres little insulation there (your lower body is fully wrapped in insulation).

    Wayne, when you say an air-pad,...

    Wayne, when you say an air-pad, do you mean like a thermarest neo-air, or would a self-inflating pad work well. Right at the moment I only have a close-cell pad since I haven't done anything more than car camping these last few years (surgeries & backpacking don't work well together), but I would like to upgrade to a prolite plus.

    I really detest mummy bags for space, love them for warmth, & I'm really thinking this might just be the bag for me.

    Best Answer

    The pad sleeve it big enough to handle the thickest pads someone would take backpacking. I think thinner closed cell foam pads like the Z Lite might not work as well but any air pad or open cell foam pad should work nicely.

    Since the pad isn't included with this,...

    Since the pad isn't included with this, where can I get one that is guaranteed to fit? Without it it is just a sleeping bag not a backcountry bed.

    Any standard size sleeping pad would work, just not the extra wide ones. What I'd like to know is if the bottom is filled or not. In the clip that they show it looks like it isn't. Just saw another review that answered my question. It looks like the area that goes right over the sleeve isn't filled, but the lower half of the bag is.

    Hey Ladies,

    I actually got a chance to crawl into one of these the other day and it is pretty rad. Heather is correct in that there is no fill underneath the shoulders but it is filled under the lower back to the feet. I suggest for these integrated sleep systems to get an air-pad instead of an open-cell or closed-cell foam pad since it will keep you a little warmer but any sleeping pad should work under the right conditions so long as its 20 inches wide.
