PS. Just in case anyone is considering a Prijon kayak - the thigh braces are large and sturdy, and I could not for the life of me get them aligned up to fit my leg. Basically, when I was sitting my thighs were angled out with my knee as the outermost point (logical, ja?), but the thigh braces were slightly angled inward. So however I moved the seat back and forth or the braces back and forth I could just achieve more or less of the brace squeezing my thigh and making my leg go numb in the long run.

So I just chucked them out. Bingo! Perfect fit

I may glue in som foam padding or something but so far the extra room to bend my knee feels perfect.
