Kelty Light Year Sleeping Bag: 0 Degree Down - 2008 BCS

This is a very good cold weather sleeping bag. I have used it in weather as cold as 5 degrees and slept like a baby. The half zipper takes some getting used to, but really didn't bother me. I am 6' tall and 185 lbs. and had plenty of room with the reg. size. Like most bags, the zipper did snag if your not careful. I am from the northeast and use it for all my winter backpacking trips. But the key to keeping warm is not just a good sleeping bag, but also a good sleeping mat. This is even more true when using a down bag. But all in all, I am happy with this product and the price is great.

This is an expedition bag for sure. I recently used this bag on Rainier at camp Muir and was very warm and cozy. The zipper only zips halfway down the bag which makes it harder to get in and out of but that doesn't matter when its -10 outside, because once you get in this baby its warm and toasty. I would recommend a lighter smaller bag for low land camping/hiking.

This is a seriously warm bag. I've only tried it in 18 degrees, but I was perfectly toasty. It's not the lightest or most compact, but for the price point, it's downright amazing. For anything slightly better, you'd need to throw down at least another $75. The half zipper takes a little getting used to, but I'd gladly take five seconds longer to get into my bag than carry another 4 ounces.

used it @ 8600 ft. in the Eagle Cap Wilderness over Memorial weekend. It was in the mid teens @ night and mid thirties by day and very windy at times. I slept very comfortably in the light year and was very warm. On the second night I actually slept with foot vent unzipped and the side partially unzipped also.
The first thing I noticed with this bag when i unstuffed it was how much loft or poofy it was. wow.
I loved this bag but with one minor complaint. It seems to be a slim cut. At 5' 9" 180 muscular. It not very roomy in the shoulders. The half zip feature I wouldn't worry about. In fact I prefer it. It zipps to about waist level. I haven't ever had a zipper past that any ways. The weght listed is a lie it is 3lb 13oz

This sleeping bag is definitely designed only for cold weather. I used it on Mt. Kilimanjaro and it was perfect, but when it came to my safari right after it was way too hot. There is a zipper at the foot of the sleeping bag that is supposed to provide a little ventilation. I used it to stick my feet out, but it was still too hot. The zipper only zips halfway down the bag. So I couldn't even open the bag all the way and use the top flap as a blanket. It was either in the bag or out. Good for cold weather only!

The half zipper drives me nuts! It probably seemed like a good idea on paper but the fact that is doesn't zip all the way down severely limits the bags usefulness. I would not purchase this bag again for that reason alone.
