I bought this pad because my thick, rei foam pad bunches up in my hammock and my inflatable pad does not do much on windy nights.

Pros
Took the shape of my hammock without bunching or slipping.
Kept my backside plenty warm with gusts around 30mph. I never felt the wind under me.
Rolls up tight.
Lighter weight than my inflatable.

Cons
If I had to sleep on the ground, there's very little cushion.

I'm going to stick with this pad, I think.
