my wife has a Palm Element w/ relief and socks. It is bomber and the customer service is just as good or better than Kokatat.
I paddle a kokatat and love them too, but palm, for 1/2 the money is a steal and well worth it...Also, I have worn this drysuit on several occasions (it is small on me) and can give you a first hand review. BTW my wife is 140 lbs, about 5'10 and she is in the Women's Large.
Palm fabric is thicker and more "bomber" than kokatat
Palm gasket material is thicker and is easier to put on/off
custy service is easy to get in touch with nowadays
you need a buddy to zip you in
the relief zipper is nice for me but I have a pee hose, not a pee hole so you will need a funnel
