I've been wanting to get a cap or two (if I need a polyester and wool). My commute often sends me straight into the sun, or has surprise rain. I want something functional, without logos or racing stripes, or any of that nonsense. I also need something with extra-large sizes, because my head is super fat at 24"-24.25". I've been looking that the Surly wool cap, Walz caps, and Octopus caps. Does anyone have experience with any of these? Any other caps that are similar that I should be looking at?
