I have a BB and love it. I like the size and weight of the Yeti and know I won't be disappointed with quality, but am worried about versatility. This may be a general question about UQ's, not sure, but with the Yeti being on side channels, is it easy to get a gap in the head or foot end for warmer nights or is it necessary to push the whole quilt up over your head or at least well out of the way to get a decent amount of air in there?
