This O'Neill Reactor USCG Women's Life Vest is black with bright purple (the photos look more pink than it is) and bright light blue accents, and it comes with a safety whistle that I attached to it. The closure is a zipper up the front with two large adjustable buckles across the front to adjust the fit. The size is specified as "6" / "Adult Small" (user weight: more than 90 lbs (41 kg), chest size: 33-36 inches (84-91 cm)), and the vest is a Type III PFD, with "Intended use: Water Ski Vest" specified inside the vest.
I have had this vest since 2013 for use when sailing a small catamaran a handful of times each year, but the boat was sold a couple of years ago and I haven't worn it since. This vest is functionally in excellent condition. It has a little bit of white discoloration from sunscreen on the front near the neckline and a stain on the small interior tag (see photos for details), hence the "good" instead of "excellent" condition rating.
