Good, but still a fair weather bag

The bag was good for what it is, but it’s not a 15 degree bag. It is a reasonably priced early fall, late spring bag though. My buddy and I both have this bag, and both of us complain that in any temps under 40 deg it’s iffy at best. We had multiple 30-35 deg nights and were cold wearing multiple layers (I resorted to wearing my all of my hunting gear, and was still chilled…3-4 layers on top, 2 on the bottom). Do not think you will hop in the bag with your skivvies and sleep like a baby (unless its 45+ maybe). If it was just me that felt this way then it would be easy to call me a….well you know. But my backcountry partner and I both had the exact same impression and we are camping several days/weeks a year. It’s a great, light, mild weather, bag from a fantastic company that should be rated at 30 degrees or higher. While the price is tempting for a 15 degree bag, don’t be a cheap skate like us. Just pay up and get a higher end (Big Agnes) bag. It’s our own damn fault, not Big A’s.

Did the job

The sleeping bag itself kept me plenty warm. I thought it was supposed to come with a stuff sack but I must have read wrong somewhere and I tried to use the Big Agnes foam pad underneath in the mesh holding spot for a sleeping pad and it didn’t fit right but again probably something I misread for those to be compatible. All in all the sleeping bag was warm and did the job.

Good quality bag. Works well with the Big A Qcore insulated inflatable mat.

Haven’t used it yet

I gave it 5 stars but haven’t used it. Bought it for September backpacking in greater Yellowstone. It’s a little heavy but I needed a 15 degree bag that wasn’t crazy expensive

Great bag for the price

Just got back from a late season Colorado Elk Hunt. Temps were in the single digits at night. This bag kept me very warm and comfortable.
