Hi Guys Working out in the pissing rain this weekend, I have ascertained that 2 of my waterproof breathable jackets are not as waterproof as they once were. The North Face one let in more water than it kept out and I was freezing, the Sprayway one (only been washed twice, and in Nikwax Tech Wash both times) let a little through but it wasn't half as heavy rain. I have sprayed both with Grangers Re-Pruf prior to coming out as per the instructions. It seems to have performed the sum total of **** all. The wash in stuff has been not-recommended as it cloggs the pores. Neither are actual Goretex, they are both manufacturers-own copies. My Army GoreTex (actual Gore) has never let water in, despite a lifetime of abuse and never having been sprayed or washed in Tech Wash. I am thus taking the Army one out in my daysack today in case of another downpour, but has anyone any advice about getting the jackets (particularly the Sprayway) back to their former waterproofness? My warm layer is down insulated so getting water on the inside is really not preferable. Or is Gore the only breathable fabric that actually works, and should I just go and flash the buck and get a Gore / Berghaus as a more permanent solution?
