I'm going to be in the Pyrenees next week... and the long range forecast is for rain. I'm presuming this is gonna be proper rain, and not the drizzle we've occasionally had in the last couple of years here in Norcal. What do the forummers on here from rainier states than mine recommend for a jacket in such conditions? I'm looking for something a bit lighter than the plastic macs I grew up riding with back in Ireland, though.
