All the flotation you need, in the lightest, most personalized fitting way. This new performance driven vest, featuring Air Foam, tips the scale at roughly half the weight of others out there - but still has enough buoyancy that will have the Coast Guard giving you a high five. The 2 to 1 foam means mobility you are used to only find from a thin impact jacket. Ronix Xperimental Technology is the never-ending pursuit of high-end minimalism - a vest that meets that standard.
