Connelly's new M-16 belt pack is even smaller than the original SUP inflatable vest! The convenient and compact belt style is very comfortable and stays out of the way while you're paddling. If you need flotation, simply pull on the tab to activate the included CO2 cartridge and inflate the bladder. A zippered storage pocket is included for carrying essentials. 16-gram CO2 charge provides 17 lbs. of buoyancy. Oral inflation tube provides additional buoyancy up to 26.5 lbs. when fully inflated. M-16 inflatable vest is not recommended for non-swimmers or weak swimmers. Vest must be placed over user's head after inflation. USCG approved Type V PFD with Type III performance. Fits 30"-52" chest sizes. For adults over 80 lbs. and 16 years of age.
