Big Agnes Lost Dog 0-30 Degree Sleeping Bag | FireLine ECO Synthetic Insulation | Lightweight for Backpacking, Cozy for Camping | Attaches to Sleeping Pad

At 6’5”, I can finally say I found a sleeping bag that fits me! I brought this bag on a back country trip, and was comfy and warm the whole time.

Amazing and warm! Love it.

I bought this for a trip to Nepal and slept in it for nine consecutive nights using a small tent of average quality. I'm 6'6" and had plenty of length and space especially given I tend to move a lot when I sleep. I paired it with a Big Agnes insulated sleeping pad and was comfortable on the coldest night which was 30F. I think I would have been cold if it were much colder although I admit I didn't tighten the hood around my head. The rating of 15F seems too low. My main beef is with the zipper. It seems small and insufficient. It consistently gets caught in the fabric and I was worried that I would break it with a firm tug. My wife bought a different model bag from Big Agnes and her zipper broke the first night and will be sent back. My bag has an older elastic system to attach the sleeping pad. It worked great and I loved it. My wife's had the new tie attachment system from Big Agnes but I didn't like it as much. One note not effecting the score, the Big Agnes system relies on the sleeping pad to provide all of the insulation from the ground. Their inflatable pads ship with a patch kit but if a seam were to blow out it could create a serious problem on a cold night. The user would be forced to sleep on the ground without insulation. In summary, I like to bag assuming the zipper holds up, especially for the space and design.

This fit my brother perfectly at 6 ft 4 and 200 lbs. With a cold weather rated sleeping pad and sleeping in two layers with doubled up wool socks he was comfortable enough in 0 degree fahrenheit. The only part of him that was cold throughout the entire night were his feet and you are pushing this bag anything below 15°. The bag was on sale so it was a good deal. If you were trying to pack more ultralight definitely get a down sleeping bag but this still packs down enough to where it's not cumbersome.

Son is 5’10. Says it it’s the perfect length.

I ended up camping in 12 degree weather the first night I used it. I was a little bit chilly, which is to be expected since that's too cold for this bag, but I slept really well overall. I can tell I'd be really warm in 30 degree weather, which is usually the coldest weather I camp in. The pillow sleeve is awesome, and I had no issues with the sleeping pad retention. This bag is incredibly comfortable, and I'll never go back to a mummy bag.

Really enjoyed sleeping in this bag over two night in Michigan. Loved the pocket for a sleeping mat which worked perfectly for my Thermarest Air. Brought back home and when I went to air out the sleeping bag, noticed two large gashes (> 2 inches) in the fabric. Not sure if this came while stuffing in the sack or during sleeping on it, but the material is very light and on further inspection prone to tearing. Will try to stitch it closed but have doubts the fabric will stay this way as it is so delicate. In retrospect, would not recommend.

Love the bag. So much that my wife ordered one as well after mine came in. Once hers came in, I noticed it came with a stuff sack. Mine did not. Obviously shipped from different retailers, but be careful. Apparently not all sleeping bags come with it.
