I've been using this bag since last fall. The 800 fill is really comfy and it kept me nice and warm on a frigid desert night in october the first time i used it and was really happy about that (i know i would have been a frozen popsicle in my old synthetic winter bag). Since then i've used it a bunch in Utah, Fruita, CO and recently in Idaho. We were camped pretty closed to a river in Idaho with no fly and I woke up to my tent mate asking if i was wet from the dew/condensation, but the drizone fabric worked perfectly to keep me dry inside and keep the down from getting wet.

A few things to note...

a) The zipper tends to get stuck and does not zip as smoothly as they intended. They are suppose to have "snag free zipper tracks" but mine seems to get hung up on the baffle quite a bit.

b)The "Regular" is made to fit someone up to 5'5" and i am exactly 5'5". The long is made for 5'11" which seemed excessive to me, but i now wish i had gone with the long for 2 reasons. For one, when my toes are pointed in the bag they are tight against the bottom of the bag, and second, since i am not a "skinny minny" (about size 14/16 up top) i would have loved the extra shoulder room in the long. I tend to end up sleeping on my side or stomach a lot too and would love to have the extra wiggle room, though i'm trying to learn to sleep on my back without moving as much, lol

c) The Bag comes with two straps on the bottom to go around your sleeping pad to keep you in place, but if you're like me and you move to your side these are useless because the pad with go with you or keep you from moving. If you can sleep on your back without moving, then im sure they are great.

Overall the good outweighs the bad and i really love this bag. (And the green fabrics/patterns are a really nice touch!)
