If you want to see something cool, check out the recently introduced M-16 by Onyx. No, not the James Bond secret intelligence agency, but it might as well have come from their labs—this M-16 is a slender inflatable belt pack lifejacket with a highly clever design.

The easy-to-use lifejacket packs U.S. Coast Guard-approved performance into a comfortable, ultra-sleek belt pack that’s ideal for houseboaters who love stand-up paddleboarding, kayaking, fly fishing, and more. Thanks to the extremely low profile design, you can enjoy your favorite activities while out on the water without compromising ease of movement. When it is not in use, the M-16 can be stowed conveniently and compactly. The pack inflates manually and instantly when needed, and includes a D-ring attachment for keeping small accessories handy. Check it out at www.onyxoutdoor.com where it sells for $89.99, and don't forget to check out their other lifejacket designs like the M-24 while you're at it.
