Customer Reviews
Compact and easy to pack. Love this ATEPA sleeping bag.It will be better if the colour can be chosed.
Sleeping BagThis is my first sleeping bag designed for back packing so when it arrived I was a little intimidated by its small, compact size and light weight, wondering how I would ever be able to get it back into the carrier bag and how it could be warm enough for camping in the mountains in late fall and early spring, so I was very pleasantly surprised after trying it out. I had no problem compressing it and getting it back into the carrier bag by myself. I am o pressed by the quality of the materials and of the workmanship.The nylon shell is soft and smooth and water easily ran off it before it could be absorbed. Since it is water repellant and not water proof, I did wipe the area I had poured water on with a towel right after it ran off. The zippers all have a flap behind them to prevent air or water getting in when closed as does the carrier bag opening. The zippers are rugged and a high quality. The side zipper has 2 zipper pulls allowing it to be opened from the bottom. I love the zipper across the bottom which lets you have your feet out while the rest of you is snuggled in. I really like the fact that it can be opened flat so it can be used as a blanket or zippered to another sleeping back making a 2 person unit.I haven��t used it on a camping trip yet so I cranked my bedroom AC and used it in a 50�� bedroom. I had to open the bottom to let air circulate and unzip the side a little bc I was too warm so I believe the comfort temp of 44��F in the description is accurate and think that it will be fine for any temp that stays above freezing, especially with a mat or pad under it. It comes with 3 sturdy straps that can be threaded through loops on the exterior of the bag to secure the sleeping bag to a mat so it doesn��t slide off while you are sleeping. There are snaps that make it possible to wear it hands free as a cloak.I definitely recommend and will update if that changes after using it when temperatures drop again next fall.
The insulation is efficient, and the bag is well-constructed. It's worth every penny and has become an essential part of my camping gear. Kudos to ATEPA!
The ATEPA bag is compact, but the down loft could be higher for better insulation.
I really like this bag. I ordered it late September, very lightweight perfect for packing and to move around with you. Comfortable and cozy enough for them cold camping nights.I was a bit nervous that it had lost its loft and warmth being in the bag but when I pulled it out and shook it out it popped right up and was extremely lofty!I was actually Hot in this bag at night but it is the end of summer in my area where the temperature is can get down to mid 50s at night.I love that you can open the whole thing up like a blanket or just open the feet or zip it closed. The hood of the sleeping bag can be zipped off a well.The zippers are big and of good quality. I'm 5.9 tall/ 195lb and I had plenty of room from side to side zipped in with lots of space to move my feet around.It is a nice quality bag and I do recommend it highly ????
