All I have is a relatively inexpensive speedometer but it must be rainproof because it survived quite a deluge. I cannot vouch for the higher end equipment other people might have. The one thing I have to tuck away is the garage door opener. I have it normally clipped to the bike but even a light rain will make it croak until it dries out so I tuck it in my pouch with my wallet etc and it stays comfy dry.
