I'm the new owner of a BB 1.0dl - yay! I have an Exped Multimat that I thought might be a good summer pad to use in the double layer, but while it seems to fit ok, it wants to work its way out the side of the layers. The pad is 40x72 and something like an eighth inch thick, if that. Seems like some Dutch quilt clips might work to attach the pad to the hammock material to keep it inside the layers... anybody got some advice on this?
