Rivendell's got a top for your dome that will keep 75% of the style from leaking out through the top of your head. It's reversible -- and it's wool -- the fabric of choice for the dapper cyclist braving inclimate weather.
It's grey/blue on one side, and a subdued grey on the other: for inconspicuous travel through the urban labyrinths of your metropolis. It's cycle chic that when placed proudly on your cranium lets others know that there's a revolution under way, and you're sporting it on top of ton tête.
