A few problems, but overall great
Bought for a late August 10-day backpacking trip to Grand Teton. Not sure I believe the 20F rating, as on some nights when it was in the 30's I woke a little chilled. Packs nicely, and for synthetic is not too heavy. Even after a couple of week use looks like new and doesn't have any nasty odors. Zips are different length on mens and womens which makes for an offset at the head when you zip them together. Overall price/performance I can see why this in The North Face's best selling bag.
