webcubus, My dry suit recently sprung a small leak in the wrist seal. I decided to do my own wrist seal replacement, so I wrote up a blog post about it. This isn't a full tutorial of how to do it - I'll leave that to the pros. This is more meant as a tips and tricks/overview of the process to help others decide if they want to do it themselves.
I've put 2 cold water dives on the new seal and it works great!
