Hello, I bought a montane slipstream made of pertex quantum. I thought that it was waterproof, and it seemed so until I got caught in a torrential downpour and i got pretty wet.
I can't say for sure, but it seemed to me that the water snuck through the seams.
Does anyone have experience with seam sealing a montane slipstream or pertex quantum, and have pointers for best practice?
Thank you!
