The Big Agnes Lost Ranger sleeping bag offers warmth to 15 degrees and features premium 650 DownTek insulation. Big Agnes is amongst the first sleeping bag manufacturers to incorporate DownTek water repellent down into its bags. Using nano technology and a proprietary application process, DownTek effectively eliminates all of the previous negative attributes associated with down. In addition to making the down water repellant, the nano treatment also provides anti-microbial and anti-bacterial protection. DownTek repels water while maintaining its loft and insulation value, even in the wettest of condiªtions The Lost Ranger includes the company's popular integrated pad sleeve system which is different than the traditional sleeping bag on top of a sleeping pad. Instead, they unite the two. With Big Agnes, the pad slides into an integrated sleeve on the bottom of the bag, and the top two-thirds of the bag is insulated in the traditional style. When insulation material is compressed under your body, it loses most of its ability to insulate. They eliminate the unnecessary bottom insulation and replace it with a sleeve to accommodate the pad which provides the insulation.

I knew going in that Big Agnes' bag ratings are notoriously inaccurate. There's a reason they don't publish EN ratings. It's obvious when you play with the bag that it doesn't have enough fill on top to make it a 15 degree bag(by design there's nothing on the bottom, of course). The top side of this bag has about 1/3 of the thickness of my Mountain Hardware 0 degree bag and on par with my North Face and Marmot 30-35 degree bags. If you read the reviews, not just here but all over and for other BA bags as well, you'll find that aside from the most warm blooded of people, the consensus is almost uniform that BA's ratings are at least 15 degrees off. That was my experience as well (see below).
As irritating as that is, you should not assume that this means it is a bad bag. It's a solid bag -- a solid 35 degree bag that is uniquely comfortable. The construction is good, the features are great, and the BA sleep system is without doubt the best sleeping I've ever had outdoors.
A good insulated pad is required because by the design the bag is not insulated on the bottom. I use a Exped Synmat 7M, and its super. The bag stays put, you stay put on it, and you can turn over without twisting up and your bottom side stays toasty. A side benefit for those that toss and turn is that the bag zipper stays in the same place, instead of ending up twisted around underneath you when you are hunting for it in the dark. The system really is as good as they say.
Sizewise, the Lost Ranger is a semi bag, so it's roomier than a mummy. I'm 5'10 and 200, and it's just fine.
Feature-wise, the integrated pillow pocket is what it is. Not terribly useful as it slip slides around. I used a Fillo Pillow and it's much better. Zippers are stout. Like any bag, you can catch material in the zipper if not careful, but BA does have some sturdier fabric along the zipper track/draft tube that helps keep it from catching unless you aren't paying attention. This isn't constructed as an expedition bag (or priced like one), but it's solid and well thought out.
Back to my experience. At the outset, you should spend some time letting the bag loft up before using it and you also REALLY need to check the distribution of the down. I had a couple of spots with little or no insulation. It was very easy to puff the bag around and get it distributed and it's stayed put since then. But take the time to do this or you'll have cold spots. The bag also gets more lofty over time (by "time," I mean over a couple of weeks from when I received it), so be sure to store it uncompressed.
I'm an average sleeper -- maybe in fairness to BA a tiny bit cold natured, but not much. Last two trips have been perfect test conditions because the temperature has started in the 50s and dropped to low to mid thirties by morning. In each case, the bag was fine until it hit about 35. Even then, I was not truly cold: I just wasn't toasty and I'd notice cooler areas if I moved around in the bag. When it got to the low 30s, while I'd live, I was clearly not as warm as I'd want.
The first trip, a light base layer made the bag work fine at 35. The next trip, when it hit 35, I pulled on a Reactor liner bag. It worked great, and probably would make the bag perform much closer to its 15 degree rating. However, there is absolutely no way that this is a true 15 degree bag. Even with a good liner and wearing a base layer, I probably wouldn't trust it to 15.
My wife has the BA Roxy Ann, which is the basically the same bag sized for women, and it's exactly the same experience. Except for someone exceptionally warm blooded, this simply isn't a 15 degree bag. It's barely a 30 degree bag.
So, my verdict is that I love the system. I wanted a 30 degree bag and knowing BA's ratings were off, I intentionally bought the 15. So, things basically worked out the way I wanted. If I wanted something close to a 15 degree bag, I'd buy the BA 0 degree bag, and probably the 800 fill model, not the mid-tier 650 fill model (like a Lost Ranger).
In short, the inaccurate temperature ratings issue is not a reason to avoid BA bags, just something to account for when you decide which one to buy.
A minor wish or two: I'd probably lose the integrated pillow. It's not a bother, it's just not that useful. BA should spend that money on another 6 oz of down. Also, BA should include compression straps on the stuff sack instead of offering a compression strap system as an option. The bag can be compressed much smaller than the stuff sack, but you'll have to buy a compression sack or use their strap system which you have to buy separately.
Lastly, in keeping with the "system" concept, there are some cool accessories from BA. The Wedgie is a carrot-shaped insulated wedge that zips into the bag and adds a little girth. It will cost you a little warmth, since it will create more dead space in the bag, but it does add some room and packs down to nothing. They also have other bags you can use as an over-bag on the Lost Ranger or as a stand-along BA system summer bag.
Lastly, one tip: To get best performance, pay attention to how much you inflate your pad, whatever the brand. If it's too rigid, not only is it less comfortable as a pad, it will "tension" the bag by holding the bottom completely flat and making it feel like the top side is pressing down on you. There is a sweet spot, where the pad is firm enough to keep you from contacting the ground with your hip bone, even sleeping on your side, but still flexible enough that the sides can bow up slightly. That way, it doesn't pull the top the bag down on you like you're being shrink wrapped. It's easy to get it right.
I am 5'8" and around 200 lbs, so, not exactly slender, a side sleeper and I do not like mummy bags at all. My current sleeping system is the Big Agnes Hog Park, which is great, but, very large, 6 plus pounds and since it has synthetic insulation, it does not pack down very small.
This bag fits perfect. I am comfortable on my side, fully zipped up. It's like a cocoon and I expect it will be much warmer than the 20 degree Hog Park, which has worked for my into the high teens. The Lost Ranger seems well made, like everything from BA. It is noticeably light but still has all the bells and whistles of its larger and heavier sibling, in a small easy to manage package.
This bag is easy to fit into the sleeping bag compartment of my 75 liter pack with room left over for the sleeping pad.
