The MTI Fluid Belt Pack 2.0 OM Life Jacket - PFD is A lightweight and comfortable belt carried PFD. Perfect for yoga SUP where freedom of movement is important. The OM includes a mini-carabiner to clip into a group tether during SUP Yoga class and a multi-loop attachment to add a water bottle. It's so compact it won't interfere with any of your balance poses and it can be worn on the front or the back. Should you need it, pull the cord and whoosh, the CO2 cartridge immediately activates and a life jacket bursts out of the pouch. Just put it on over your head, it is tethered to the belt pack around your waist so it won't float away. The 3D mesh padding is soft and quick-drying to prevent chaffing. There is a zippered storage pocket for chapstick, sunscreen, or a snack. The OM is so comfortable that it's also great for cruising the lake on your paddleboard, kayaking, and fishing.
