Travel light, move fast.
I'm a minimalist.
Just did a Caribbean liveaboard with this checked bag and a small under-seat carry-on.
No wheels, don't need 'em.
The backpack straps allow me to move gracefully through crowded places.
Best to travel under-the-radar, so I don't use any luggage or clothing with a scuba logo.
I feel no need for anyone to know I'm a diver until I get to a boat.
Packed inside are my BP/W, Aeris Accel Fins, high-top booties, 3mm full, 2mm shorty, spare mask, two BigBlue lights and charger, a spare inflator, SMB, and a couple t-shirts.
No tools, or additional spares. There's always someone on the boat who's packed a small hardware store.
Regs, mask, batteries, and a good paperback book go in my small carry-on.
Documents, IDs, phone, charging cable, ear plugs, bits and pieces,
all go into the multiple pockets of my thrift store travel vest.
Disclaimer: I don't travel with U/W camera gear anymore.
I live in the moment.
