Hummingbird too tight for comfort? Check out the Swallow or Swift for the same great features with a little more room.

Everything I Hoped It Would Be!
I ordered my bag on Monday 9/5 (Labor Day Holiday) Customer Service said to allow 6-9 days... I told them I had a back-packing trip 9/14. I received it 9/10, the following Saturday! Very nice customer service rep. 4 day trip in the Sierras. Backpacking up to 8,500'. Lowest night - 28 degrees. I was warm without layers of clothes. I didn't even mummy myself in the bag. Just wick dry shirt and legs. I'm 5'9", 170-lb. Hummingbird YF 20 degree, regular bag. Plenty of room. I will continue to use this bag into winter without fear of temperatures in the teens. I dropped 3lbs off my pack and I've never been as comfortable. Thank you Feathered Friends!
This is my second one. I loved my first one and it burnt up in the High Park Fire in northern Colorado. So I bought a new one
Hummingbird sleeping bag
Well-made product, the company obviously takes a lot of pride in its work. The sale was easy and professional, and they made sure that I was satisfied
Exceptional quality YF20
I received this bag in only 4 days. Customer service was impeccable and friendly (over Christmas, when everyone is under pressure). The bag itself is on a different league. It is ridiculously light, well made, packs very small and its rating is conservative (I've used it in 15 F and was fine, with base layers). I am super happy with it and cannot recommended enough. Save a bit and go for it. Thanks.
