Sea Kayaker recently had a favorable review on an inflatable version. You might look into that.

: Anyone out there ever seen a hip brace pad that will take different shims of
: minicell foam? It is like a packet. One velcros around each of your hip
: brace "panels" and allows you to adjust how tight your hip
: braces are easily. It would be a great addition for someone who shares
: their boat. I would like it because in the winter I could remove a
: 1/4" shim from each one to better fit cold weather paddling clothing.
: I think the white water paddlers use them more. Please post if you know
: the name and/or website where I can look at them.
