Thanks for a very good and revealing thread. I have exactly the same problem with my TNF jacket I bought 4-5 years ago, and I thought I should add some pictures and quote what they said. I suppose those in Australia and Europe have the same problem (in the US the warranty might be better).
When I first e-mailed VFC.com in Belgium (who import TNF), Barbara at the Customer Care Team said "As far as I know, we do not have an issue with the lining of TNF jackets.". But then I read about the problems in this forum and other places and told her it is called "de-lamination" and apparently well-known.
Then Jolien Dusauchoit at the warranty dept. wrote "I think in your case the problem might have been you washed the product not enough." and that I should have washed it "maybe even once a month if used almost daily" to avoid delamination. They said I was welcome to send it to them since their repair service can re-laminate some jackets, and that it was ok to wait until the winter is over. I wore it this winter even though wherever I go it looks like I have a severe case of dandruff..
I had washed only the fleece since the rest looked and smelled clean, and I had always used 2 layers of clean clothes underneath and only used it in the city when going to/from work etc, i e maybe 1 hour per day, not breaking a sweat, so even with this new requirement on washing monthly if used much, it should translate to at least 4-5 month intervals in my case if just counting the hours (several years if counting sweat). I decided to send it to them via their brand store in Gothenburg (since the store where I bought it decided to stop selling TNF). The owner said, before sending it, that he didn't think it was possible to repair, and that they recommend washing every 4 months. He also said the cause for delamination is it being dirty but that this can't be seen due to being black - very interesting how this thread with the light jacket reveals this lie. I e-mailed VFC and said the jacket is on the way but by then Jolien had stopped working there; instead Sylwia Chalupka wrote that they recommend washing every 3 weeks (!).
Today, when I collected my unrepaired jacket, the sales clerk confirmed they don't include any instructions that says they are to be washed neither every 3 weeks nor every 4 months. The
EU care instructions say "How often should I wash my Hyvent® garment? Wash your garment as often as you need to remove such impurities as dirt, campfire smoke and cooking odours. Washing and drying your garment helps restore the durable water repellent (DWR) that is important to the performance of a Hyvent® garment.". The
US care instructions don't mention hyvent but says for shell jackets "In order to revive the DWR, the product needs to be thoroughly cleaned with a powder detergent (do not use a liquid detergent) in a regular washing machine in warm water.". Nothing about need to wash it every 4 months or 3 weeks to avoid it getting ruined by delamination. If they really do need such extreme washing intervals (assuming they are not making up these recommendations as they go) it should be clearly stated in the jacket and on their web site.
Another thing the owner of the TNF shop in Gothenburg said was that it is normal to wash this often just like you wash a pair of jeans. First of all 4 months would be much for a pair of jeans but they would smell by that time if used daily. But a better comparison is with my 15 years old DKNY cotton winter/autumn jacket, which has never been completely washed, just dabbed some parts around the throat a couple of times (it's the only part that gets in touch with the skin, and only if no scarf).
So I guess the conclusion is that TNF is not for every day use, just for outdoors adventures, accompanied by washes about 10 times per season, unless you think €250 is ok for something that lasts only 4-6 years. Gore-Tex does not have this problem from what I've read.
