Can't answer the supply questions about who and where to buy, but I can
answer the important questions. Yes, you want to add a relief zipper.
In kayak gear, you have to take off you PFD and skirt to use the
zipper, I had it added to my Kokotat Whirlpool Bibs and it's the best
money I've spent in a long time. The first thing that happens when you
get a drysuit on it that you will have to pee.

Booties are great and I'll never own a drysuit without them. They make
the suit much easier to get into and your feet stay dry and much
warmer. I have latex booties on the bibs and have not had a durablity
issue with them, but I am careful. If I had it done today, I think I
would opt for the goretex or goretex clones socks instead of the latex.


I had KoKotat install the relief zipper and booties while they were
doing some warrenty repair for me. There are a couple of companies that
advertize on BT that replace gaskets (a job you can do yourself if you
have the time) , they may do the zipper also. I assume that all of
these companies are US based.
