I bought this rectangular bag because I like to sleep on my side and a mummy bag will not accomodate that sleeping position unless the bag follows the contour of my body. Big Agnes put plenty of thought into the design of their sleeping bags and it is very noticable in the Lost Ranger! I get the best sleep from this bag with its contoured down collar, 3" zipper draft tube!
I also purchased the Exped 7 sleeping pad and these two products together are a match made in heaven.

Like the previous reviewer I bought this bag because I a) sleep on my side and b) toss a lot in my sleep.

The integrated sleeping pad holder is perfect and the material is cut so there is plenty of room to move around yet is still close cut enough to be warm. The zipper works well and does not snag much. So far the workmanship seems solid.

I have only taken it down to 30F but I was plenty warm then wearing just the lightweight smartwool long johns and long sleeve shirt.

As an added bonus I can zip it up to my wife's Agnes and we can sleep in a shared bag. Done this once already and will be doing it again soon.

Bottom line, there are lighter bags out there but this one works for me.

I am a big guy (6'3, 330 lbs). My goal was to find a bag that would keep me warm but had enough room that I didn't feel like a sausage in a casing...

This bag is great! I bought the long version (which is a bit wider too) and the matching air core pad. (they make an insulated pad, but it was a bit heavier and more expensive)

Set up is very easy. There is a slit at the bottom of the sleeping bag so you can stick your arm in and pull the pad through the built in sleeve. (I found it was easier to partially inflate the pad first)

The first time I set up and slept on this sleep system, I was freezing cold and thought I had made a mistake purchasing it. Turns out, I didn't have the pad in correctly. The pad inserts inside a built in sleeve in the sleeping bag that starts about where your shoulders would be. Once the pad is all the way in the sleeve, you have to kind of bend it to put the remaining part of the pad in the sleeve where your head will be (if that description makes sence). I did not do this; I just put the pad in the bottom half of the sleeve and called it good. Well, during the night the pad shifted away from my feet and I got COLD! After figuring out that the pad has to be ALL THE WAY IN THE SLEEVE, it was the most luxurious night of backcountry sleep I've ever had!

The hood is very effective at keeping your head and face warm without making you feel like you are being suffocated. There is also a nice little sleeve positioned under your head where you can stuff a fabricated pillow or a makeshift pillow out of your sweatshirt or something.

Only downside I can even think of is the air core pad makes the sleep system a little tall. It would be absolutely perfect if big agnes made the air core pad about 1/2 as thick.
