I’ve been riding around with my rain jacket from my cycling days for the past month. It is PERFECT for motorcycling. It is so good I’ve been meaning to do a review of it for this site. As it’s marketed for cyclists it is not something you are likely to see reviewed on typical motorbike sites, but if you think about it the needs are pretty much the same. In case you missed my original post, it’s a Gore-Tex Bike Wear Pack-Lite jacket. Okay it’s not exactly cheap (retails around $250) but I’ve seen it online for a lot less. And I believe this is the premium rain proof material (according to mountaineering types whose demands are probably more exacting than ours) so there could be alternative brands out there that work well enough for us. Might be worth popping into a local bicycle shop for a look.
