Okay, here's the scoop. I bought my vespa about two months ago, and in a fit of frugality (so I could afford the dang thing), I skimped a bit on my accessorizing. I bought a cheapie helmet and a cheapie armor jacket. The helmet (a plain old 3/4) is now relegated to my "around town" pile, for speeds under 30 MPH, since one or two trips on my regular commute (speeds up to 60 MPH) put me in the mind to get a FF helmet.
This past weekend, I was forced to ride in the rain (I was 60 miles from home, at a MSF safety course, and it started to rain on the way home). After nearly 90 minutes of riding through the rain, I discovered that my jacket is not waterproof. Or even water resistant. Not even a little bit. The jacket is a cordura textile thingy with CE armor in the shoulders, elbows and spine, and I was soaked through in a matter of minutes. Luckily the air temperature stayed in the mid-60s, I wasn't cold. Just wet.
So I'm thinking about either (a) getting a new jacket or (b) treating my existing jacket. The jacket itself is fine, it's reflective, reasonably stylish, and fits okay except that the elbow/forearm armor is about an inch too low - I have to shift it up manually and cinch down my velcro straps to hold the armor over my elbows. I've got very short arms. Option (c) would be riding with layers - putting a poncho or windbreaker over the armor jacket. I've got a nice paclite shell that's very lightweight and weatherproof (I use it for backpacking), and that fits on top, but it's not all that satisfying, frankly.
Anyway, I've read a lot of reviews about jackets from a comfort / fit / style / safety perspective. What I'm interested in is hearing about weatherproofing and sealing options. I'm hoping to ride my scooter in as many weather conditions as reasonable, since the alternative is riding the bus, and there are at least three days a week that I can't work from home.
So - anybody have any ideas? The Corazzo jackets with the 1000 cordura shell report that they're "water resistant", which is a start.
