Given all the other gear you have, why not spend the $200 and get a waterproof bag for the times when the weather looks a bit dodgy but you still want to play?
I have a Titleist Sta-dry and it's a fine bag to bring on trips to places where it might rain.
The caddies don't complain about the weight and it has enough storage to keep all my blister tape, anti-inflammatories, Nuun tablets, stretch bands, rain gear, gloves, balls, and tees 😆
