bizarre! when i bought skele they were half the price of azz!
the skele pads i got, are kinda in a slinky stretch material girdle, so there is no slip or movement; but it is completely porous and thus breathable; i think it is quite efficient at moisture wicking too.
the padding itself is dense foam and there are no out plastic shells; this seems to have no ill effect on performance, but allows complete freedom of motion, without getting an edge of a plastic plate whack you in the gonads....
Just coz you don't understand it
Doesn't mean it makes no sense!
