Lighter Weight And Warmer

[This review was collected as part of a promotion.] Saved me 2 pounds on my pack, packed in smaller and kept me warmer than previous bag at a great price. Upgraded from synthetic bag which made a world of difference.

Great Bag!

[This review was collected as part of a promotion.] Love this bag! It’s light weight, packs very small, and the fabric is very soft and comfortable. I’ve used it a few times. Love the space at the feet too!

Great Entry Level Down Bag

[This review was collected as part of a promotion.] It’s a huge upgrade from the typical synthetic bag most grow up with camping. Highly recommend if you’re looking to get into a down bag without breaking the bank.

Very Good Option In The Market

[This review was collected as part of a promotion.] This I have bought for general camping in Texas area camps, and also planning to use this during Summertime in the Grand Canyon. This is very light weight and suitable for backpacking which is the biggest advantage.

Narrow And Not Warm

[This review was collected as part of a promotion.] Used this on my last camping trip this bag was thin, I could feel cold spots at each rib seam my feet were incredibly cold and I could not sleep well. I and a med-large male with 44 inch chest at 5’7” this bag was so narrow at the shoulders it was unbelievable. I feel like this bag for a teen child in 50-60 degrees is a more fitting description. The zipper is designed to be worked from the outside not really the inside which means you have to contort yourself to close it all the way up. Additionally it snags on the baffling behind the zipper. I had high hopes for this one due to weight and design but it did not live up to the name or described purpose.

Nice Lightweight Bag For Warmer Weather.

[This review was collected as part of a promotion.] It is sewn through design and not baffled but it is not a cold weather bag. For most people this bag should easily be good to the upper 40's. I'm not sure I would take it much colder than that but I sleep cold anyway. There is also a real nice zipper guard that keeps the material from catching in the zipper.

Good Budget Down Bag

[This review was collected as part of a promotion.] This bag is a great introduction to the world of down filled bags. The price is great, it packs down to a small size and is lightweight. I wouldn’t take it in the winter but it should be fine as a three season option. The reason I gave it 4 stars is because it is a tight fit for me despite buying the long version (I’m 6’5”).

Solid Bag At Affordable Price!

[This review was collected as part of a promotion.] I was looking for a lightweight down mummy bag for spring/summer camping. Budget was pretty tight so stayed away from the Big Agnes etc. This bag is perfect down to about 35 degrees F. I suggest having a small blanket as well. Packs super small and looks good.

Budget Fluff

[This review was collected as part of a promotion.] Very compact and most importantly down jacket. Purely for warm weather. in 2021 they replaced the down from 600 to 550. But from the positive they made a more practical decoration. And it was important to move the pocket under the phone in the middle (now it is bigger). Took it to replace a synthetic sleeping bag. In fact, the comfort temperature is close to 50 F. I would not recommend it for early spring or late fall.
