I've been keeping my eyes on the gear sales going on this season and though this might be the time to upgrade my sleeping bags if a good deal pops up. Currently I've got a Marmot 40* for summer and an REI 15* for winter. Both are mummy bag styles and I have a really tough time getting sleep on hikes in them. I'm more of a side sleeper and tend to roll and shift in my sleep.

I started looking at the Big Agnes bags since they have the wider foot box. But the other thing that is unique to them I see is that they have little material on the bottom side of the bag. Instead they have a sleeve built in that you slip your pad into. They claim with this system you never roll off the sleeping pad, which sounds great.

Anyone have opinions or experience with their bags? Or have similar sleep situations and found som other solution?

This is their 50* summer bag:



and the 0* I'm considering
