Yesterday I took a ride in the cold rain...I had on 3 layers of wool and my showers pass jacket...my keens over..yup..merino wool socks... and my regular fingerless gloves. and my helmet of course...
The most uncomfortable part was my fingers..YOW!! cold cold and wet...so I just spent my last dime on a pair of gloves from sierra tp...Marmots.

What do you use under your helmet to keep your head dry?

and all this talk about softshells...esp by other PNW riders ..which softshells work the best in the rain? I'm pretty comfortable in my showers pass jacket..it seems very breathable...but just in case?
