First off I would like thank the people who supplied helpful info on my search for a 2 person tent.

As the traffic is getting heavy in some of the parks I love to hike and camp in. I have decided to do more backpacking in the shoulder seasons. Realizing that this will put me into colder temperatures. I need to look for a warmer sleeping bag.

I have been looking into this bag and it looks like a good design. Before I part with the cash. I would ask if anyone has experience with these bags?

Thanks in advance

A friend of mine has it and loves it, his one small complaint is the opening at the bottom to cool your feet, it does not always close resulting in cold feet. Having said that his feet are always cold so this might not apply to everyone. It is nice to see some new ideas for the sleeping bag design. Let us know your experience if you end up with one. Have fun.

Thanks runningclouds I will surely let you know
