My wallet's been at the bottom of the med for nearly 40 years:It's not just cyclists that have this problem. My son in law's phone is at the bottom of Lake Garda!
Anything valuable like a wallet with all your cash & travellers cheques, in a shorts pocket that's overhanging the side of a pedalo.
One of the reasons I don't have a smart phone is that the screens are too small, and the phones are too big.although I enjoy the large screen (failing eyesight) it's way too big to just fit in my jersey pocket
