Recently was the first to purchase the Z-10 sleeping bag. I had waited 8 months to purchase it when I heard they had been redesigning they're 4 season bag.
I can't emphasize how awesome this bag is! It's incredibly comfortable, it's light as hell, it's stylish, and most importantly ITS WARM!
The first morning I woke up in it I had 8" of snow on my bivy and our temp gauge showed -18 (which including the bivy adding insulating values) was spot on! I was toasty and had no cold spots what so ever.
I highly reccomend anyone to purchase this thing, i'm absolutly in love with mine and it will be back out this coming weekend on Sneffels, Red Cloud - Sunshine or Handies peaks.
