Recently introduced by Onyx is the M-16, a slender inflatable belt pack life jacket. The easy-to-use M-16 packs U.S. Coast Guard-approved performance into a comfortable, ultra-sleek belt pack that’s ideal for pontooners. When it is not in use it can be stowed conveniently and compactly. The pack inflates manually and instantly when needed. (www.onyxoutdoor.com)
