Warm but a bit snug across the chest and arms

I have used this bag for 2 trips, recently and have found it to be very warm, but a bit too narrow across the chest and arms, to the point where, if I am wearing anything thicker than a T-shirt, I have trouble zipping up the bag from the inside. It is just downright claustrophobic for me, has no ventilation other than the one zipper, and prevents my ability to move around, so I will be ditching this bag and going back to my Traverse bag that is much heavier, but also more comfortable.

Comfortable and warm

[This review was collected as part of a promotion.] This is the only sleeping bag made of artificial material that I've ever found comfortable. It's not too slippery or noisy, and it's very warm. It immediately fluffs up really well. And it's shockingly lightweight for its loft. 100% recommend.

Excellent balance of warm and lightweight

[This review was collected as part of a promotion.] I bought this for a mild winter backpacking trip. For 3 seasons I have preferred a quilt and layers of clothing but I needed something warmer for winter and early spring/late fall. I am a back sleeper who struggles in the confines of a traditional mummy, yet I carry extra sleeping bags, food, and occasionally water for my dogs so I don't have weight to spare. This bag was wide enough that I didn't feel trapped while very lightweight and warm.

Flame Ultralight Sleeping Bag

[This review was collected as part of a promotion.] This is the best sleeping bag I have ever bought. It is very affordable, great looking and packs up amazingly small and light. I love it!

Zipper came off 1st zip...yikes.

[This review was collected as part of a promotion.] Zipper came off 1st zip...yikes. but got it back on. Slept great in 30 degree weather overnight ...in prep for steelhead fishing in Erie Pa. Roomy enough for a side sleeper, that's me :)! Warm and snuggled especially important for a raynauds sufferer. 1st trial in the bag was great! Next adventure...Appalachian trail!

Cozy

[This review was collected as part of a promotion.] Kept me warm and was easy to sleep sideways. My zipper did get stuck on night 4 and my bag tore. Thankfully, a friend had a repair patch.

[This review was collected as part of a promotion.] Is a great prduct. I’ve just bought it for my 12 years daughter, and she’s so happy with it, easy to keep, light and really warm.

Miserable sleeping bag

I bought the Flame 3 sleeping bag, comfort temperature -4°C for backpacking in the summer: I spent a month in the Swiss and Slovenian Alps (June/July) and a month in Iceland (August). Every single night that was below 10°C I froze in this sleeping bag. I had to use the silk sleeping bag, wear Merino underwear and usually also the down jacket so that I could sleep. This was truly the worst purchase of my life. I have a Marmot sleeping bag with a comfort temperature of -4°C in which I have never felt cold, even at sub-zero temperatures. These sleeping bags are two different worlds. I would not recommend this Flame 3 sleeping bag!

[This review was collected as part of a promotion.] Very lightweight for backpacking! I also love that it comes with (2) separate bags for storage!
