I have the Equenox waterproof full chaps. Not quite waterproof trousers but I have a pair of these (cheapo ones from local farm shop) and they're awful. Yes, the trousers are totally waterproof but they make my legs sweat like hell underneath, its disgusting! Whereas the Equenox chaps are so comfy so ideal for riding in. They have fleece inside so keep your legs cosy too. I would think they're unisex.
