Enjoy a good night of sleep anywhere!
The Ghost is a marvelous, very warm sleeping bag. Its outer shell keeps your away from humidity and the excellent down filling makes the bag feel like an oven as soon as you slip in it, even on a frigid night. A very good bag for high altitude mountaineering, I would recommend it to anyone who wishes to look at the stars from high above the clouds while keeping heart and feet warm!

This is one of the best sleeping bags I have ever purchased. I have spent many winter camping nights in this bag on and off mountains. Due to the laser seams it doesn't have any cold spots, the conduit fabric wicks moisture very well, and it has kept me warm and dry. This bag is worth it's weight in gold!!!

I love my Ghost Sleeping Bag.
I stayed nice & warm on our last expedition to Aconcagua, and my Ghost was put to the test many nights with raging winds and blowing snows. The Conduit coating also kept the moisture out and me nice & dry. I am only 5'3" so I would have liked a shorter bag as I found cool air creeping in to the extra space near my feet. Also it would be great if there was some way to make the zipper easier to do up as it always seem to get caught in the material. Other than that though I wouldn't trade my Ghost for anything!
