Waist belt buckle: www.mcmaster.com 1 x 4’ absolutely necessary
Fins are a Yes
Mask & Snorkel a very good idea
Swim Cap or neoprene hood also good to retain body heat.
Neoprene spring suit x 2mil thick
Reef walking shoes, see photo
Waterproof Aqua-Shirt, long-sleeve, from Victory Koredry another fatigue saver from sun and saves core body temperature. Hoodie style keeps the sun off and is better than hauling a hat. Although a hat with a strap also works, just another lose thing.
Basically, while you walk or climb you have your water things attached to your waist strap.
While you swim you attach your walking things to the strap always having 2 free hands.
Nice mention on the Kore Dry Technology site
Even the mainstream media Laguna Beach Independent has picked up on this event
