I've never really had a problem with any of my suits except for my new xcell drylock 4/3. It seems they had a problem in their production process because some of the exterior lock-stitching is unraveling... like their machine wasn't doing the lock properly or something. No ill effects yet, but I'm keeping an eye on it, I plan on sending it back to them this spring in hopes they will have it fixed and/or replaced by the time I need it this coming winter.

I have also noticed it looking a little funny around my left elbow--probably from putting direct pressure on it while driving my car with my left elbow on my arm rest.
