What a great sleeping bag

I have 7 sleeping bags acquired over 50 years of backpacking and the Hummingbird is finest. The construction is top quality. Unlike the zipper on my other bags, this zipper is a really good design and it does not snag. My first trip was hiking the Big Bend Outer Mountain Loop with the temperature down to 11F and I was comfy (with clothes on since I sleep cold).

Almost perfect! but earns 5 stars anyways

For reference ai am 5’-6” 150 lbs. athletic build. Literally just came back from a backpacking trip to Wayne National Forest where temperatures went down to low 30˚. I tend to sleep on the hot side so only wearing base layers but was kept nice and toasty in the Hummingbird 30. No complaints in the warmth department. Space was enough for someone my stature to allow for movement and turns as I do often change my position during sleep. Packs down as small as my pillow taking little space in the backpack and weight next to nothing as well. Overall, I am extremely happy with the Hummingbird 30, but only wish it had a pocket inside to keep my phone warm when temps hit below freezing as they did this past weekend.

Just incredible! Perfect 3 season bag!

It’s my first 950+ FP bag, it just packs down to nothing. Everything now fits in a 20L backpack for a weekend hike. And it’s warmer than I thought. I think it’s a perfect 3 season bag! I read that it can be snug, but for me it fitted just right. I'm 172 cm ~ 5′8″, 72kg ~ 159lbs.

Hummingbird 20

Really happy I picked this over the roomier swallow, just the right amount of room for me with a bit left over for layering (140lbs 5’8”) The quality of construction and materials is without fault, my only criticisms are minor in the hope FF further improves this fabulous bag. The zipper plow does does do a good job preventing fabric snags, but it’s slow and a bit clunky to operate. I prefer the oversized dual fabric stiffeners running the length of the zipper on WM bags as a snagging solution, paired with a smooth operating standard slider. Arguably a 20 degree bag ought to have a proper draft collar. There really is none whatsoever on this bag, so when you need it to perform at its warmest it’ll mean cranking down the hood tight around the face. Personally I’m happy with none, knowing that I can add an insulated jacket for easier comfort when nearing the bags lower limit. When temps are regularly below freezing I’m switching to a warmer bag anyway. But for folks wishing to use this bag below freezing without the help of an insulated jacket, I would recommend considering alternatives with a real draft collar. Lastly, I wish FF would offer at least three length options. 5’10”, 6’2”, and 6’6” I think would make a lot of people happy with a more accurate fit. Overall a lovely bag I look forward to using for many years, thanks feathered friends!

Excellent. It seems like an ideal 3 season bag for backpacking. Perfect combination of lightweight yet very warm and just roomy enough.
