If you are like me, a bigger guy, who likes to sleep on his side, yet stay warm and be comfy all night, then you will love the Big Agnes Lost Ranger 15. I have gone through a few sleeping bags in my life. Before backpacking I was drawn to square bags because I had a lot more room to move around, I wasn't worried about bulk since I wasn't lugging it along the trail and warmth never seemed to be an issue. But things changed once I discovered backpacking.
- Very light for its size.
- There are lighter bags this size
- Occasional zipper snag
When I started backpacking I read that I needed a mummy sleeping bag, a pack, a pad, and a tent. Those were the main 4 things I needed for a night in the back country. From there I didn't do much research and bought things mainly based on what I could afford.
I ended up with some off brand sleeping bag from eBay, which did the job, but could have been better. The best thing it did for me however was open my eyes about sleeping bags and what I really needed and wanted. In the end I wish I did more research so I didn't buy that first bag. But hey, at least I have extras for my friends who want to come along.
One of the first things I was looking for in a new bag was more space. While many have more width around the shoulders not many are as wide as the Big Agnes modified mummy shape. In short it is a more squared off mummy bag which gives you more room in the foot box and shoulder area. This was great as I could now roll around a lot more in my sleeping bag and was a lot more comfortable at night. I am 5'11" and went for the regular sized bag and it was the perfect size. If you are in the 6' range, go for the long.
Another factor in choosing this sleeping bag was weight. While it isn't the lightest sleeping bag at 2lbs 14oz, it wasn't too bad considering the extra room. Big Agnes does that by adding a sleeve pad on the bottom side of the bag in place of the filling. When in your bag laying on your pad, you are squishing all the filling so it doesn't loft up and keep you warm anyway. Instead you rely on your insulated mattress pad to keep your backside warm. A nice little bonus is you don't slip off your pad at night. This bag is also 650 fill goose down, which is lighter than synthetic fill.
Keeping me warm at night was also of utmost importance. The bag itself is rated to 15 degrees. But as many people will tell you add about 10 degrees to that if you are a guy and 15 to 20 if you are a woman as the lowest temperature you would expect to be warm at in this bag. So in this case I figured the bag would keep me warm down to 25 degrees. Again, this is with an insulated mattress pad.
I have taken this down to the mid 20's and have been plenty warm in it. I don't think I would test it in much colder weather though. Another thing to think about, this bag is bigger inside which means there is more space to for your body to keep warm and an greater chance for cold spots. For me this hasn't been an issue, however after doing some research, it has been an issue for some.
There are other features on the bag I like too. The zipper is a nice burly zipper YKK #8 zipper which doesn't get caught often. I have had issues with the zipper catching, but not as many as other sleeping bags I have had. There is a draft collar to keep cold air from blowing down your bag from the hood. It has a pillow pocket in the hood so it won't slip out of your bag. A draft tube along the zipper keeps cold air from coming in between the teeth of the zipper. It also comes with both a stuff sack and a big cotton storage sack for when it isn't in use.
If you are wondering, this bag does have its weak points. The cons about this bag are, for the price you can find a lighter bag, but not with as much room. The zipper still snags even though it is a nice YKK zipper. The stuff sack is a basic sack with a toggle and draw cord. So if you are looking to really cinch down your bag, you will have to buy a different stuff sack. ou can only use square sleeping pad for the sleeve in the bag, so you can't cut more weight using a mummy shape pad.
With all that said, I still think this is a great bag for the money and if I was in the market for another bag, this would be at the top of my list. Big Agnes did come out with another bag that piques my interest though, the Mystic SL. The SL is for super light and they achieve this by using 850 power fill goose down which drops the weight of the bag 10oz to a scant 2lbs 4 oz, while retaining the same shape and extra space I have grown to love from the Lost Ranger. But costing $160 more, I think I am okay with the extra 10 oz.
Of course on the other end of the spectrum is the Encampment 15. Same dimensions as the Lost Ranger and Mystic, but with synthetic fill. This bag weighs in at 3lbs 4oz but is $80 less. Might be an option for those on a budget, or for those who have a chance of getting wet since down doesn't keep you warm when wet, but synthetic does.
Either way you go what I have stated above, along with Big Agnes quality I am sure you will enjoy any of those bags.

Bought this bag from Lees Adventure Sports in Kalamazoo. Used it in the fall and winter in Manisttee, Michigan; very warm bag on cold nights slept with a fleece liner. Also invested in the BA insulated sleeping pad.
I'm a big guy, 6'3 and I had plenty of room to roll around in. Very impressed with the quality.

Fill: 650 down
Temperature Rating: 15 degrees F (I'd rate it more like 30 degrees F)
Weight: 3 lbs and change
Price Paid: $209
I bought this bag because I'd always wanted a down bag and was intrigued by the Big Agnes sleeping pad system. Spent five nights in it where the temps got into the upper 20s lower 30s. I know temperature ratings are not a precise science, however, I would rate this bag more as a 30-35 degree and up bag. I did get cold even with long johns, poly pro layer, and a wool cap.
I did like the roominess and that I wasn't "Mummified" into the bag. I'm a side sleeper and didn't really have any problems rolling and turning. The drawcords on the hood were a bit uncomfortable on my face when snugged up tight. The integrated pad worked nice. I never slid off once. Very comfortable on the ground to lay on.
My biggest gripe is I've had the zipper snag about once a use. I've tried to be careful with the zip. Overall a decent bag. If down bags weren't so expensive I'd like to buy/try some others to compare.
Excellent 4-season bag that lives up to its ratings.

Excellent 4-season bag that lives up to its ratings.
- Very packable
- Pad doesn't slip out
- Great for tossing and turning
- Works with my NeoAir
- Zipper sometimes snags on wind baffle
I have been backpacking 10,000'+ over 45 years in the California High Sierras with the last 30 in down mummy bags. This is the first packable bag that I have found to be warm while allowing me to toss and turn without slipping off of the pad.
Coupled with my NeoAir (which is lighter than my BA pad), I am sleeping more comfortably than ever. I just leave the NeoAir in the bag and compress it all. So far it has worked very well. I have been warm when sleeping with temps in the teens; I use a 3lb 7oz tent which helps a lot.
I especially like the pillow pocket where I can stuff my soft things to use as a pillow without it getting away from me in the night as with other bags. The hood is great — just limits my tossing a bit.
Because of the large top, entry and exit are very easy and I can easily roll over.
I have used this bag for twelve week-long 10,000'+ trips, having purchased it used on EBay for $130 three years ago.

This bad boy does it all for me. Roomiest 'mummy' type bag I've ever experienced!
- Warm...down to 10 degrees without liner
- Comfortable...has room for your feet!
- Built-in sleeve for the pad
- Big across the shoulders for a 6'l/200 pound dude
- Left hand zipper on this one? But hey...
Great sleeping bag. Your pad fits into a sleeve on the 'bottom' of the bag so you can't roll off of it in the middle of the night. Super comfortable! If it gets cold there's a hood that you can crank down on your noggin.
Like I said, I've had it out in 10 degrees/on snow...don't know if it's rated that low...and that was without a liner...with the liner I wouldn't hesitate to give 0 a try...but that's me.
I've got llamas carrying my gear, so this one might be a bit heavy...but I recommend it without hesitation. Don't know why I'd ever buy another bag!

Let me start by saying, Big Agnes makes some seriously tough products. I bought this bag three years ago now and have used it every chance I've had since purchase.
The bag itself is of unique (to BA) design. There is not down fill in the "back" portion of the bag. Rather, there is a pocket for an air pad of your choice (does not have to be a mattress from BA. ie; Thermarest, etc). This makes for a lighter packweight on those long, rigorous trails or thru-hikes. In that aspect, its a benefit, when it comes to keeping warm true to its rating, it can become its downfall.
I tried Thermarest, BA air mattress, and a few others, but none seemed to fully fill the mattress pocket to keep cold air out UNTIL I got my BA Insul Core mattress. Finally, the bag not only keeps me warm in its intended 20F but even kept me warm (with no additional liner) at a very cold 8F!! It's great! To anyone buying this bag, keep in mind it is down, so moisture can be an issue.
The bag's skin is water repellent but that doesn't mean water can't seep through and soak you. With proper mattress, freezing cold is no issue. And because of the design, you save weight. On warm summer nights you can ditch the pad altogether!
All in all, this was a great purchase. Very much worth the money. Hope this helps you with your purchase.

Very comfortable sleeping bag. I like not rolling off the pad.
I used it in the Adirondacks on a cold Columbus Day weekend (temps in the low 20's) along with a lightweight down sleeping bag liner from Western Mountaineering. I tend to sleep pretty warm, and with the liner I slept very (but not overly) warm; bottom line, even for a warm sleeper like me, I am not sure about the 15 degree rating...
One thing to note about the Big Agnes system: I was using the bag in a lean-to. Because the pad slips right into a sleeve on the bottom of the bag, it was a bit more of a pain the butt to roll it up in the morning, so I didn't. That turned out to be a little unfortunate when the snow blew straight sideways into the lean-to -- I came back to find a fair amount of snow on the bag.
Moral of the story -- be less lazy than I was, or throw the bag/pad combo in the back of a lean-to along the rear wall.

Excellent, light, warm, but when coupled with the Big Agnes Air Core sleeping pad, my toes end up getting a bit crunched (could surely use some extra room down there).

Temperature Rating: +5

When discussing down sleeping bags, it's always worthy to mention that each of us sleeps at different temperatures. I sleep hot and always have. Others sleep cooler and require more insulation.
For me, this bag rocks. I extend its season easily using a military gore-tex bivy cover I got on Ebay for $25. The bivy easily adds another 10 to 15 degrees and I've slept comfortably in my bag to just above zero.
It's also important to note that a significant amount of heat loss occurs through your head, face and neck at night in the cold. The bag works to correct this with neck baffles, but you should always consider adding a balaclava or stocking cap when sleeping in immediate cold. I also add a layer of polypropylene in extremely cold weather because with the Gore-Tex bivy, you need all the help you can get to wick moisture away. Nowadays, learn to sleep smart and include this bag or one like it in your plans.
Everything the marketing says about this bag is true - you can turn over easily in it and it is fairly wide for big chested men. I would have included a gear pocket for things like lip protection and eye glasses but overall, I really like what Big Agnes has done!

Weight: 3 lbs

I got this bag last week and used it for the first time this weekend. Everything I read about the bag is true:
- Big Agnes makes the most comfortable bags on the planet. The sleeping pad sleeve (coupled with the Insulated Air Core pad) changes camping for me. I've never slept better while camping.
- The small pillow sleeve is genius. I stuffed my fleece in there and had a perfect pillow, that didn't keep falling out of my bag.
- The bag is definitely not a 15 degree bag. As others have mentioned, add 15 degrees to Big Agnes ratings. This is a 30 degree bag (which I'm fine with, because I'm not a winter camper). It got into the mid 40's on my trip and I was actually a little warm in the bag (had to unzip it).
- I love that I can stuff the sleeping bag and pad together into the sleeping bag bag. Works great. Packs tight.

I am shorter than six foot tall but have very broad shoulders, so the room this bag provides is perfect for me. However, it wasn't perfect for staying warm on a night that approached the temp. rating. I would say this is a 30 degree bag, and I sleep warm. Bottom line, a great bag but add 15 degrees to temp rating.

This has become my new favorite bag. I have a few down bags and they are the only type I use for backpacking, but this one truly stands out. The concept of the pad sliding into the bottom of the bag is not only a great idea, but very functional. Several reviews said it is like sleeping in your own bed. While that is a slight overstatement, it is close to the truth. This bag is not only comfortable, but roomy. I bought two, so could zip together with my wife. Works great.
I did buy the 15 degree pad and was impressed with the comfort. It did take a little effort to blow up, but the plus side is a thicker pad that you can truly lay comfortably on your side. I am really surprised that more sleeping bags do not come with this type of an option. No more sliding off the slick pads... Worth every penny!

I recently overnighted in an AT shelter using this bag and insulated Big Agnes inflatable pad. The shelter floor was wood planking and I used a nylon bag cover to protect the sleeping bag from dirt, etc. The temp got down to 28 degrees F ( according to my small thermometer)and I froze in that bag!
I was pleased in the roominess but what is that worth if you are freezing!!? I even got up in the middle of the night and put my silk bag liner in but to no avail. The pad was also very cold to the touch.
This bag is rated by Big Agnes at 15 degrees--maybe they mean centigrade and not farenheit! I would not recommend this bag to anyone who plans on doing any cold weather camping.
