Sorry...just now seeing this. Someone asked awhile back about my Rodney Powell and whether or not it feels like cardboard. Cardboard, no because to me, cardboard is flimsy!
It's stiff. But once you wear it awhile, your body heat begins to mold the foam to your shape. When I first put it on, I feel like I can't breathe. I've lost quite a bit of weight, so I may need to order a new size. But they are slightly adjustable as they fasten from the size.
Those Tipperarys are comfy, but they feel (to me) like you're not wearing anything. What's the point in that?
