The Cushion is working very well.
I thought it was Pe LePera because of the low price, but I felt secure in the Fu Caphka.
It's shaped like a Helmet so it's not as bulky as the square HelmetBack.
It is written that it can be used with a large cap, but the RX-7X M is just about right and there is not much room for it.
With XL and System, it's going to be a patsy.
