Thoughts on this one - I have a Seeland Jacket(Lingfield) which I bought several years ago, probably at least 5 years or so. The last 2 or 3 times i've had it out in the rain i've come back wet through, particularly middle of the back area. Its presumably not the seams that are leaking, more so its the actual waterproof membrane. No point in treating it with nikwax etc as thats really for the outer fabric rather than the membrane. Im inclined to email Seeland although I read from their website that the warranty wont cover 'normal wear and tear'...whatever that means. Has anyone else experience of Seeland customer services? As a slight aside i've got a couple of goretex jackets and similar 'membrane' items of outer clothing which are probably twice the age(perhaps even longer) than the Seeland and theyre still as waterproof as the day I bought them, never even used nikwax or reproofing on them either.
