hi all, i've had a ME sleepwalker two that i have not used for 2 years, i went camping recently and found it a bit cold and remember reading about not storing your bag in its stuff sack. which i have done.

have i knackerd mine and is there anyway i can breath new life into it.
cheers

Try hanging it on a nail on a door for a few days see if the puffyness comes back, failing that maybe a wash and tumble dry to bring it back to life,if label permits?

Suggestions made by Diddy might be worth trying, but it sounds to me like it's a goner.

If it has lofted back up it is probably ok. I bought a Firewalker II a couple of years ago. The first one I had wouldn't loft after removal from the stuff sack. Even days later, parts of the insulation were pancake flat despite much shaking. I had it exchanged and the replacement was fine. It's possible the bag's not at fault. You might have been tired, dehydrated or hungry or the air might have been very humid, all factors that can affect how warm/cold you feel when in a sleeping bag.
