Hyper Lite competition wakeboard/water ski vest. I didn’t wear it much. It always fit my chest to tightly. I’m a 36B. This vest is regulation for water ski competitions and on private water ski lakes. It is not regulation as a PFD (personal floatation device) on a public lake. It provides some float but not a significant amount. The skier/swimmer/surfer must swim while wearing it. It does not have a zipper. It’s a pull over style with a corset-like sench. It’s very cute with subtle designs.
