Buying used drysuit
I'm looking at a couple used drysuits (O'Neill Boost). How do you inspect the seals and zippers to make sure they are in good condition if you can't do a water test? What am I looking for other than cracking? If I ended up having to replace seals or zippers, how expensive are those repairs and are they effective? I want to make sure I don't fool myself I'm getting a good deal on a used suit only to spend more money than I would have buying new.
