I bought a Sugoi Hydrolite jacket a few years back, and it was wonderful. It scrunched up into nothing, and it sort of puckered up when it rained, which meant the rain didn't get in, but I didn't overheat either. I liked it so much that I bought another one in a slightly different size, which was just as well because the waterproofing started peeling away at the lower edge, which rather defeated the purpose of the rain jacket.
But this year it stopped puckering, which means it doesn't block the water any more, so it's like riding wearing a wind-resistant sponge. Do I just throw a $100 rain jacket away, or is there anything that can be done to repair it?
