Cycling in the rain / rain jackets? So I bought a (relatively) expensive cycling waterproof jacket about 18 months ago - after quite light use (I only wear it in the rain, it's not my everyday jacket) it now lets water through. It got me through many storms without any issues but now it's as though the coating/waterproofing has worn off...is this normal for cycling rain jackets? Or did I buy one that was too cheap/bad manufacturer?

Anything I should look out for when buying a replacement?
