What piece of non-diving gear do you never leave behind on an ocean trip?

Every diver has a specific non-diving item that somehow always makes it into the gear bag—whether it is a specialized thermos, a lucky hat, or a reliable windbreaker for the boat ride back to shore.

When facing cold offshore winds right after a dive, slipping into warm, comfortable post-dive layers makes a huge difference. High-neck zip-ups like team argentina world cup jackets have become a personal staple for cutting through coastal breezes while keeping things lightweight and easy to pack.

It gets me wondering about everyone else's surface-interval setup:

• What is the one non-aquatic item you refuse to travel without on liveaboards or day trips?

• Do you prioritize heavy thermal insulation, or do you lean toward lightweight, windproof outerwear?
