Will start with some Wynnster waterproof pants. In large byt good enough for xl bellys. With elasric bungee cord waiste which still works nicely. Might do with a reproof but seem to be holding off water well (only tried em under the tap just now and didn't bead up... but then again I never remember em ever bwading up water but do recall em protectin me from all sorts of nasty weather).

Velcro closures around ankles to keep chain out. Fatter ankles are better but worked fine for me
