Great bag! Very warm and very snug. The best thing about this bag is its weight. I took it with me on a recent fishing trip specifacally because of its light weight, since I had a ton of fishing gear to carry.
It got pretty cold at night where we were since the wind was blowing off of the water, but since this bag had no zipper I had no issues at all with keeping warm. Since it was so cool at night I cinched the drawstring hood all the way down to keep warm since we didn't use a tent. The only drawback to this was the fact that I woke up the next morning to find that I had tangled and knotted the drawstring cords during the night somehow and no matter how much I tugged at them, they would not budge, leaving me trapped in my sleeping bag since it had no zipper.

Even though this is a very snug fitting sleeping bag due to the elastic bands around it, I was never uncomfortable at all during the course of my trip. It actaully proved to be beneficial to have the bag so snug that way when I tried to move the bag moved with me. I managed to hop over to where my friend was fishing to see if he would help me, but he just laughed and said I deserved to be stuck. I remained stuck for most of the day until after several hours of pateintly trying I managed to untangle the cords. I was so pleased with how comfortable this bag was that even after getting stuck inside the bag for most of the day I had no reservations about using it again that night. I used it all week long and was never uncomfortable once.

Overall this is a great sleeping bag and I highly recommend it. Its weight and warmth are top of the line and easily worth the price!

Design: Mummy
Fill: synthetic, I think
Temperature Rating: 30 degress F is about right
Weight: just over a pound
Price Paid: $199

Great due to no zipper, but if it is too hot out venting your legs is impossible, so I sweat sometimes. Crazy light and packs down actually to a grapefruit size. You get made fun of sometimes using it but light is right!

I'd love the winter version if anyone has one to sell, the Snowlight.

Design: Zipperless Mummy
Fill: 775 Down

Version reviewed: X-Long

I initially had to return the regular size bag (which was supposed to fit persons up to 6'0") as it did not accomodate my 5'10" frame. The X-Long model was a perfect fit and has been a godsend. There is no zipper, thus the low weight, so you have to slide in , but the "flex" design allows me to roll around, bend my legs and sleep in all the odd positions that I enjoy. I slept comfortably in 50 dgree nights in the Huachuca mountains and stayed toasty warm into the mid 30s in the Sierra Nevadas. If you are a warm sleeper, which I am, you may need to throw an arm out every once in awhile, but again, the "flex" design accomodates this. The pricetag is what I've come to expect for quality gear, and the low weight is a definite incentive.
