For those who like to side sleep or toss and turn, I'd suggest looking at a MontBell Superstretch bag in either down or synthetic. They've made the bag bigger than most mummys and then sown in bungy like material to snug it up around you. Net result is you can pull your legs up to fetal position, roll around, sleep on your side and the bag follows you. In my experience this has made for a MUCH more comfortable night sleep than I've ever had in a mummy before. You can also get by with a "cooler" bag as its comfortable to sleep with the hood in place. Also, I dont know if they still make them, but I think Sierra designs had licensed the "strecth" concept and made a few similar bags. I have no relationship with Montbell, just like their bags.
