The Alto belt pack flotation aid is a great new product from Spinlock, and very different from anything else we’ve seen on the market. A manually inflated flotation device offering 75N buoyancy (ISO12402-5 50N Approved), worn in a simple, lightweight and compact belt pack around the waist. Gone are the days of wearing a bulky buoyancy aid which restricts your movement. This new generation of flotation device will give paddlers extra peace of mind and safety on the water without having to restrict their paddling experience.
