John, I'm not sure I understand your use of the term "wet through." To me, that implies water is penetrating the suit's Gore-tex barrier and is getting you wet on the inside of the suit. If what you mean by "wet through" is that the outer layer of fabric is becoming saturated with water, but the Gore-tex barrier is still intact and preventing water from passing through it, then the suit is working as designed.
What you say is the same as Kokatat said when I shipped my Meridian suit to them for possible warranty replacement: "no delamination, so no warranty problem".
When I got it back from Kokatat, I turned the Meridian suit inside out and did a water test with the suit on a large piece of cardboard on the back patio. Within a minute or two I could see the inside fabric scrim getting wet everywhere.
Wetting through is quite a simple idea, and it's not confined to drysuits, in my experience. I've had GoreTex jackets wet through at the shoulders, GoreTex pants wet through in the seat, etc.. Notice how many commercial fisher-persons wear GoreTex vs 'rubbery' PVC foul weather gear. Gore-Tex just isn't very waterproof. And it doesn't 'breathe' when it's covered with a layer of water, either.
Once water is 'sitting' on the outer surface and saturating the fabric threads on the outside, it 'wicks through' the 'breathable membrane' (GoreTex or eVent, etc) and via capillary action it wets the clothing layers inside. This isn't a situation of a few pinholes or small leaks - I've checked and there's no localized leaking - the entire inner layer of the suit is damp/wet. When I renewed the DWR finish on my Meridian, the 'wetting through' problem disappeared for a few paddles, then returned. I repeated that DWR treatment to convince myself that I wasn't 'imagining' the result. Once the DWR allows water to saturate the outer fabric, the suit isn't fully waterproof.
I don't sweat very much when exercising and now I usually can judge the right amount of clothing to wear under the suit when paddling, to minimize sweating.
I 'retired' a drysuit a few weeks ago. After a day paddle, just the normal amount of splashing and a bit of rain shower left me with base layers
very damp. With the new replacement suit - my 'spare' of the same model-, similar conditions the following week, my base layers were dry at the end of the day and I could have worn them to the post-paddle coffee get-together without changing them. A couple of days after that, I did some in-water rescue practice with the new suit and I was bone dry inside.
In May 2018 I was on a trip where it rained ('solid rain', not just drizzle) pretty much every day. For camp wear I had 'rubbery' rain gear; my paddle partner had brand new 'top of the line' $$ Helly Hansen 'Expedition' GoreTex jacket and pants. The GoreTex gear wet through completely and was replaced once we got back home.
Some years ago friends took the PaddleCanada Level 3 course with SKILS, out of Tofino. It rained hard every day.
One of the participants commented to me that 'everybody' had wet (GoreTex) rain gear,
except for the two instructors who were both wearing heavy-duty 'rubbery' (PVC) commercial fisherman-style raingear.
There's a message there!
