are there any simple point and shoot cameras with a simple little lenscap on it?

let me rephrase that.  simple point and shoot fully waterristent/waterproof camera.  You know.  those cheap sport cameras.  Not looking for a gopro.  Just a small one that can go in water.  With a lenscap.  I am thinking one of those lenscaps you have to remove by hand.  any out there?

The Olympus Tough TG-6 is fully waterproof and shock-proof.  It comes with a lens cap.

You can install a 40.5 mm thread adapter CLA-TO1 that allows use of filters or two accessory lens ( and any 40.5 mm lens cap )

Under 9 ounces, so nice light-weight pocket sized camera.
