I own an extra ENO and would like to try it.

I was thinking of simply using velcro to attach a CCF to the bottom of the hammock, this would prevent the pad from sliding around.

Or make the hammock itself part of the bottom insulation rather than hang insulation under it? I think that building an UQ using the bottom of the hammock may cause your body weight to compress the loft but there must be a way around that.
