I just finished proclaiming my love for my Brooks saddle on a different post, when I remembered that I'd been meaning to ask a question about my beloved Finesse. I will be moving from Los Angeles to NYC shortly (probably in December). How do Brooks saddles hold out in the rain and snow? Must I cover it with plastic (or, as a former DC messenger friend suggested, a UPS waterproof bag)? Is there a comparable saddle (in terms of comfort) that is made of a synthetic material? Must I cover any saddle that I use? Ladies, what saddles have you found to be comfy?
