The Obrien Tech Neo CGA Wake Vest is their thinnest, made to hit the safety numbers for buoyancy without being so bulky you can't move in it. No easy task, but they pulled it off with a 4-way stretch neoprene, dialed segmenting, and hinge points that won't interfere with your riding. Zip up the full front zipper, adjust the two hidden security belts, and hit the wake knowing you're in one of the most advanced safety vests known to the planet.
