I'm really happy with this bag. It packs down quite small, and I slept comfortably on a 40 degree night with 50+ MPH gusting wind in just underwear. Could easily go a lot colder with some wool base layers on. Regarding size, I am a hair under six feet tall and just barely fit into the Regular. Any taller and I would need the "Long" type. I like the hood design and drawstring that really lets you snug it down and cover up your head if you like. No flaws I can see (other than that it could cost less) but good stuff costs money.

This is a great sleeping bag. I have used it in 20 degree weather with a t shirt and shorts and was comfortable, i never have zipper problems and when it gets wet it dries out very quickly

warm throughout. light enough for the trip. room to sleep. cant say enough about it. have the womans version. worth every penny!!!!!

I'm 6' tall and needed the long for a little added room because I don't like to feel confined when I sleep. I slept great in this bag for two nights in the Rockies. The first night was in the low to mid 20s and I was pretty warm. The second night was warmer (mid 30s), and so was I. If I had not been so tired, I would have shed my lightweight thermals and opted for sleeping in my underwear only. Instead I just unzipped the bag a little and went back to sleep.

Overall, it was a great buy since it packs small, is roomy enough for me and is lightweight.

This bag packs much smaller than my synthetic 20F. My friend was nice and warm at 32F. The regular is enough for him at 5'8".

I didn't think having a women's bag would make much of a difference but it really does! My feet are always cold in mens bags but in this bag my feet stayed nice and toasty! The only thing I don't like about this bag is that the chest is really roomy. It's a plus because there is a lot of room to move around, but it doesn't warm you up as fast. Over all I would say it is an amazing sleeping bag and I love it!

On Rainier we were gettin' pounded with 60 mile an hour wind gusts and I was chilled to the bones. Hoped in this bag and was warm and slept the night through within minutes. Super light and provided enough room to move around a bit.
