Exped 20°F Waterbloc 800 Down Sleeping Bag - Waterproof, 750 Fill Power, Mummy

OK, at first I didn't really like the shape of the bag around the face but after some adjustments it works well. This bag is rated even warmer than its 20 degree name; men to 15 and women to 25 I believe. The baffles on this bag work great they are full of down and have great adjustments. The Face baffle isn't as comfortable as some, it seems to be designed for very large headed people or for those who don't like a very small hole to breath from. When you cinch it up small the cords can bother you both in length flapping around and across your head/face. It also isn't a smooth fit it gets all bunched up. But if you relax it a bit its much more comfortable and with the larger hood you can move the hole away from your face so that you are breathing warmer air and not having the opening directly on your face. The bag is extremely light at 3 lbs especially with the stiffened zipper area and wind/waterproof flaps. It is quite easy to zip and unzip and I've yet to get it caught on the bag. It lofts very high and feels quite plush. You may not even need a pillow with this as the bottom neck baffle is very full and feels like a down pillow if you slide into the bag a bit (I'm only 5'8" so I have some space to move up and down). Because of the loft and tapered fit there isn't as much room to move around in the chest area ( my Chest is 40-41" for reference) but it isn't constricting either. I like the ability to unzip from the bottom and stick my feet out so I could use this in moderately warm conditions also, but as I'm a warm sleeper I don't think it would work for me to use in the warm summer nights. It is Very pleasant to lay in unzipped with the top flipped back, unlike some mummys, so you can lay in it comfortably opened and almost feel like you are in a regular sleeping bag not a mummy bag. The waterproofing and wind proofing work well too. The other night I put it on our covered porch and the wind and snow were howling around... no drafts whatsoever and the neck baffles sealed the air in quite nicely. The snow drifted on the bag and melted but didn't soak in at all, Quite impressive really. After that if you're an ultra-lighter this is a great bag and you really wouldn't need a tent at all, the storage bag is a mosquito mesh so you could lay that over the opening if there were bugs. The stuff sack isn't really a compression sack as they claim its just a waterproof bag like you'd buy to put clothing in. If space is an issue you should buy a real compression bag and this thing will compress much smaller than what is listed. If you're looking for a warm 3 season or moderate 4 season bag that is lightweight, pack-able and waterproof for a great price look no further.
