Thanks for all of your input. Seems like the verdict is pretty much unanimous. They don't work. Glad I didn't have to spend $60 to learn that lesson.

For now, I'll just keep using my old military bag. Consists of two mummy bags and a multi-layered gortex bivy bag.

Rated for 40 below for 4 hours sleep.

But definetly not for the Lite Gear talk on a forum dedicated to light gear. If you pack the whole thing it weighs over 6lbs.! We don't get 40 below weather here, maybe wind chill of -15 or a little more, but I was hoping to take a winter trip to the Rockies, or even a guided trip in AK. It is nice and toasty when the weather here drops in the teens, but again it's not light weight, was designed for young strong troops, not middle aged men. The stuff "sack", would probably hold most peoples gear for a 3 day trip.

Plus it's a real pain to zip and unzip everything. Especially if nature calls in the middle of the night in the dark and possibly, snow. frown
No fun at all.....

Thanks for your input, and saving me some $$....
