Customer Reviews
This is a pretty good bag and much better than many "value" bags on the market. It is fairly lightweight and has a good feel to it and the hood/zipper works well. I wouldn't trust this bag near or below freezing as it likely wouldn't be comfortable at those temps. The bag fill is only 55% down though and is 45% polyester. Seems misleading as I don't see this mentioned on the listing. Maybe this is standard for "down" bags, but it seemed odd to me. Otherwise I like the bag and think it's a good mid-range option balancing warmth with being fairly light and compactable.
Super light , compact, very warm, easy to store in your bag and go! Very soft and comfortable! I would highly recommend
This is a nice bag. It is duck-down filled and the rating of about 43o seems to pretty reasonable. I'm 6' tall and 200 lbs and the bag seems to be a pretty decent fit. Broad enough for my shoulders but certainly no extra room.The design is nice. I like the "3D" footbox that puts a flat bottom on the bag which makes feel nice having my feet in the bottom of the bag instead of them being a little cramped like bags that taper at the bottom.The current price of about $130 with the current coupon makes the price pretty reasonable for the style of bag. It seems to be of similar quality to name brand bags but more affordably priced.I really like how compact the bag is making it great for backpacking at just over 2 lbs.Overall, I'm happy with the "ATEPA Ultralight Down Sleeping Bags for Adults with 650FP, Cold Weather Waterproof Backpacking Werable Mummy Sleeping Bag for Camping, Backpacking with Compression Sack".
My husband loves this so much he is going to do a YouTube review on it.I recommend this product.
Very nice sleeping bag. Comfortable, easy to pack, and keeps you warm.
