Mountain Hardwear 2nd Dimension 15°

I have slept in negative tempertures with this bag and it has held up to my surprise. Even once with no tent in the snow in thirty degree weather, that's when I found it to hold up well against moisture. It packs real nice and it sleeps just as well. It seems with crazy legs it fits your body alot better. And it does not damage your bank account to bad. It is well worth it to buy this bag.

I've had this bag for quite some time now and I love it. It's a great bag for the price. It's quite warm also. I was suprised sometimes how warm it was when it was freezing outside. Only complaint I have is that the zipper catches a lot, which is a pain. But other than that it's a great bag that stands up to to its temp rating.

A nice bag that lives up to its temp rating, a compresion stuff sack is recommended to tame this bag. Also the zipper snags an average of 72 times a trip (yikes). I paid extra for Conduit SL cover, very water resistant and windproof but does not keep zipper from snagging. A good bag for people with large bladders.

I have used this bad boy in many cold and wet places, since I live in Washington, and never once have I woken up cold or wet, even when my bag is wet. I think that this is a best buy for 3D fill bags.
