This isn’t as much of an issue for me, as I’m in the tropics, but I used to ride up north in a black helmet, black wetsut, and with a black board.
There was a fatality over the weekend where a kiter was caught in offshore winds and swept out to sea in Connecticut. Details here:

A sad ending to a terrible story.
But there’s something to think about here - the coast guard found his kite almost immediately, but not him. He was wearing a dark drysuit, and of course it was dark out. The found his body the next morning in the daylight, right in the middle of their search grid; and the coroners report says he likely survived until midnight.
Several other kiters related stories of coast guard helicopters shining their search lights directly on them, but not seeing them in the dark water. This guy lived to tell the tale:

As the premiere drysuit manufacturer, perhaps Ocean Rodeo should check out putting some of those 3M reflective strips on the shoulders and arms of your drysuits. Maybe you’ve already got them; I can’t tell from the photos, but the stuff on the MEC cycling jackets is almost blinding when you shine a car headlight on it - that kind of stuff can only help.
Anyway, keep up the good work! Just thought I’d pass this along.
