Exclusive Membrane Inflatable Technology (MIT) and durable high-tenacity nylon face fabric provide a lightweight and flexible fit. The waist belt adjusts to accommodate outer layers, and large arm cutouts allow for full mobility. A manual inflation cord lets you deploy it by hand when needed. The simple 1-fold design makes re-packing a cinch when it comes time to recharge, and safety checks are easy with the inflator inspection window and access flap. When inflated, the MIT 100 Automatic Inflatable PFD provides 28 lbs of buoyancy and will turn most wearers face up.
