Here we have a buoyancy aid that we bought for our son to use when on holiday. He's outgrown it now at 15 (and nearly 6 ft!), and needs a larger size. I've copied this from another site:
An easy on, no fuss, front zipped pfd the YAK Blaze is super lightweight, stylish and practical. With full 50N buoyancy the Yak Blaze has a slimline design, high cut to allow all round movement, has adjustable shoulders for a custom fit and internal pocket for safe storage of keys making it an ideal, entry level buoyancy aid for all paddle sports.
