Drybag recommendations?

I don't know if what I want even exists. I want a dry bag for snorkel gear (scuba fins, mask, snorkel, boots). However, I want it wide enough to also fit my drone and flykit. Most I can find are only for snorkel gear. I would also ideally like it to have outside mesh pockets to drain water from the boots and fins.

Any suggestions are welcome as I have been looking for a while.
