So like a year ago I bought some of the pricey Precip pants. I used them about 10 days (only a few hours each day if that) and they ripped at the seam near the ankle.

I should have taken them back to REI/Marmot but....I didnt. And in all fairness I think they might be too long and they rubbed to rip the seam.

Anyway the stitches didn't rip, but the nylon tore along the seam. Whats the best fix to make these puppies last long enough to get my money out of them?
