    Big Agnes Lost Ranger Sleeping Bagis rated3.8571out of5by21.
    Rated3out of5byfromBig Agnes... bags for small peopleI am a big girl. ~260 lbs and 5'6... so I'm pretty heavy, I'm fat. But that doesn't mean I don't want good camping gear and that doesn't mean I don't backpack or want a down bag. I work as a Geologist and spend a lot of time in the field. I shopped... for months, I went in, I tried on bags and finally the folks at REI sold me on the Big Agnes brand. My husband expressed some doubts because this bag must be coupled with the sleep mat as it has no insulation on the bottom but as I like the sleep mat I did not think this was a problem. It was. Just got back from the inaugural trip with this bag and will be returning it tomorrow. Quite literally the worst two nights I have ever spent while camping. Without the mat, this bag is nearly perfect and if they made this bag with the normal insulation on the bottom just the way it is it would be great but once the pad is put in and inflated the bag is pulled fairly tight to the surface of the bag and restricts movement. I tried letting some air out and letting the pad be a little loose... that just ended with my hip on the ground and me still unable to breath or move... I kept letting air out until I was literally laying on a flat pad on the ground. Then the fact that I was laying on a flat mat with no bottom insulation took over and I spent the whole night shivering and trying to find a single position that did not leave me bruised. I failed. I don't think I slept more than 4 hours between two nights. I suspect if you are smaller it might be alright but I absolutely hate this bag. It gets a 3 star rating because it is a high quality bag, well made, etc... just totally unworkable if you are over 200 lbs.

    Rated5out of5byfromGreat bag...plenty of room for da big guys!I've had this out camping on snow and no cold problems here. I brought a thermal liner along 'just in case' but never got it out of the stuff sack. This bag is nice and roomy for a 6'1/200 lb guy. The pad in the sleeve is genius as far as I'm concerned. No more waking up sleeping on the ground because I slid off the pad. I'm using a Thermarest 2 1/2" pad (hey I have llamas) which provides plenty of insulation...hoping to move up to the Big Agnes before an August JMT trip if REI gets them in stock...hint, hint. Best bag I've ever had...highly recommended.

    Rated4out of5byfromSized right, works right.)Right size(not too long so foot box works well) and right pad (4.5 R rated).... just awesome!

    Rated4out of5byfromYes I will recommend.Great comfort in a small package. Make sure you take advantage of system design, ie pad insert, to have bag perform to spec. It's worth the extra 11 OZ.

    Rated4out of5byfromgreat bagI've used this bag in all kinds of conditions, I've even woken up with everything frozen outside. for the people who have problems with being too cold, try sleeping with less clothes on. I learned in a school, and from experience that less inside the bag is warmer.

    Rated5out of5byfromLight and warmI got this for my climbing Mt. Baker in August. It was rainy and not too cold until we got to base camp. Once I set up the tent it was cold. I got my mattress and insert to the bottom of the sleeping bag. Settled in comfortably and got to sleep. It was so warm and getting hot so I have to open to get fresh air in. I love it.

    Rated5out of5byfromGreat Sleeping BagI recently decided it was time to start gearing up for Backpacking, & quickly found out the Sleeping bags I currently owned were not going to work. After attending a Class on Backpacking I found this bag came highly recommended for Bigger people like me, 6'2" & 250lbs , So after some more research I decided to go ahead & give it a try, One of the best things I like is the internal Sleeping pad sleeve , No rolling off your sleeping pad, & thus far It has kept me more than plenty warm. In addition it even stuffs down to a manageable size allowing more room in my pack for those other comforts.

    Rated2out of5byfromBig Agnes-Time to Own UpI don't usually write reviews for the gear I own, and I own a lot, but after my recent experience with this bag a review is definitely needed. Big Agnes, you need to recall these terribly inaccurately temp rated bags. I just returned from a four night backpack in the Sierra Nevada where we experienced overnight temps of 29-35 degrees. No problem for a 15 degree rated bag, right? Soooo wrong. I am a warm sleeper, even in winter at home I use a light blanket but I was FREEZING using this bag in temps that should not have rendered this bag unusable. At best this is a 40 degree summer bag. On the first night my feet, calves, and knees were frozen stiff. My shoulders, even with the bag cinched to a barely breathable hole, where very cold as well. On the second night I wore almost every stitch of clothing I brought with me and I was still cold. My feet were so cold I really feel that there is missing down. And before anyone questions my setup, I use the recommended BA Air Core insulated pad AND a foam pad under the BA pad. There's no reason this bag should have failed as miserably as it did in 30 degree weather. I give this bag two stars for it's roominess and comfortable fit but everything else is an epic fail. I will be taking the bag back today for a different bag from a company who accurately reports their bag temp ratings.
