I like the minimalist approach. I look for sales, but I do try and have the right clothing for the situation at hand.
I find arm and leg/knee warmers to be very useful since it can go from kind of cold to pretty warm here.
Shorts or bibs, rain jacket, wind jersey, and a fleece jacket get me through most really cold days, along with unpadded tights over the shorts.
Gloves are a must, as are shoes, even though I will easily wear stiff soled athletic shoes for a spin on the touring bike.
Jersey if I feel like it, wicking compression shirts are bought on the cheap.
Brain bucket is mandatory.
I need to order prescription shades.
