Andrew --
I bought a couple of new tuiliqs from Brooks Paddle Gear a little over a year ago. The web site doesn't seem to be working, but the contact at the time was Mark Jarvinen; mark@brookspaddlegear.ca The phone answers: 778-727-1245 .
If it helps, I have a few older, but serviceable 3mm neoprene tuiliqs that are not being used. If anyone has need. A couple are Brooks; one is from QajaqJapan. They're all size large, with skirts to fit a slightly lengthened Greenland coaming.
