I recently look my Big Agnes Lost Ranger or to Philmont with our scout troop and I have to say it's the best night's sleep I've ever had outdoors! Between the quilt and sleeping bag, there are several configuration options to accommodate a wide range of sleeping temperatures, and the pillow sleeve is clutch for keeping your pillow where it should be at night! There were a couple nights out in Philmont that temps must have dipped into the upper 30s and I was plenty warm. I wish the zippers were a little more robust, but that's my only complaint, and it's a small one.
Bought this bag for my boyfriend who is a very hot sleeper so he could have the option of using both bags when it’s colder or just the one for warmer trips. We took it with us on the Teton crest trail and that was a huge mistake, it never got below 30 and he froze almost every night, I was in my 15 degree bag and I’m always freezing and plenty warm all night. I don’t know how they think 50 degree bag plus a 40 degree bag makes 15 but something isn’t adding up here. Returned it and will be getting something else
