I know this is covered well somewhere, but the more searching I do, the overwhelmed I get. Then I get sidetracked with so much information.

I am new to hammocking, but have great ground gear.

I got a HH Expedition.
It is a single layer, so if I use a pad, it is inside with me, that seems uncomfortable to me.
I don't plan winter yet, so I would like to know how to make or buy something tat would hold a pad (or any insulation that works 3 season) to the underside of the hammock. If it would also work in winter, that may be an added bonus.

If you point me in the right direction, I will do my homework.

Ken in NC, where there are plenty of trees.
