Will you be contacting Level Six about the latest failure of the drysuit? They do say their products come with a lifetime warranty.
"Been there, done that". In the earlier parts of this discussion about the leaks in the wrist area- with clear documentation of water coming through the fabric-I posted the Level Six response. I'm assuming that the suit seat would still pass the 'blow it up and spray soapy water' test, and I would have wasted $50 in shipping costs.
Perhaps my expectations are too high, but I haven't had good luck with suit problems and warranty service.
I soured on Kokatat after my Meridian suit started 'wetting through' in the chest and back once the DWR coating wore off. I sent pictures of the saturated suit (outside and in) and then I sent the suit to Kokatat for warranty inspection. Their report: "Passed testing, no problems." They returned the suit with both wrist gaskets shredded.
Similar 'wetting through' in the torso with an earlier (5 years ago?) Level Six suit got a verdict of 'it's worn out', but they did give me a discount on a replacement.
I think double-layer seats are probably a better bet for 'breathable fabric' suits. The alternative is a fully waterproof fabric like the Chillcheater Aquatherm fabric which has worked well for me, though it seems better for cooler weather.
In general -over many years of use (and disappointments

) I've found that 'breathable' fabrics aren't very waterproof if there is contact and pressure. For instance, my Gore-Tex anoraks/rain jackets all leaked under the pack shoulder straps. It's almost back to the days of canvas tents which were waterproof - unless you touched the inside surface.
And it's not just me. My paddling partner on a wet 2+ week trip had a brand new Helly Hansen "Pro" GoreTex rainsuit which didn't do the job- and that was just worn around camp. It was replaced with a more 'rubbery' suit (Grundens?) after that trip.
I notice the Cronos is now $950 CAD.
