I've tried doing a few searches on the subject but it would be useful to get some more info/advice.
I have a 4 year old berghaus goretex performance shell - over the last year or so I have noticed it delaminating over the shoulders, cuffs and bizarrely in the peak of the hood. I did not know that was the term for the bubbling but I have the shell in for repair of the zip at the moment and they confirmed this.
The shell has been machine washed at low heat twice and never tumble dried (reactivated using an iron on a low setting through a dish towel as recommended by gore tex), and neither machine wash or iron in the last 18 months - though it has been hand rinsed in cool to tepid water in this time.
So, is there something I may have done which has lead to the delamination?
Will there be any benefit in using reproofing agents to squeeze some more months out of it?
How can I prevent it if I buy gore-tex again?
Is there anything I can do about the goretex guarantee/is it worth doing anything about it?
I know exactly the shop it was from but no longer have the reciept or tag (it being a 4 year old jacket and I have moved a lot in that time) so taking it back to the shop for advice on this probably isn't an option. The coat has damage to an arm from a fall, which may void the guarantee anyway.
Thanks for any thoughts.
I am a student so don't have much money to spend so I realise might be unrealistic in expecting a waterproof to last more than 4 years
I am getting the zip repaired whatever as it will at least make it faintly useful, if not as a waterproof.
