Hoping to stay in the sub-$300 range. Treated down and/or water resistant materials preferred. 58" or wider top width.

I've been enjoying experimenting with a Reg/Reg EE Revelation, but as a side/active sleeper, the regular width (54") causes a bit too many inadvertent drafts. I'm also hoping that some added width will be able to drape over an inflated sleeping pad for some more insulation in cold conditions. The regular requires tucking under my body and leaving the pad edges exposed, which introduces cold spots early in the morning.
