The Assault life jacket combines stability and full lumbar support to keep you completely secure when hitting wakes or jumps! Lightweight and stylish, ONeills Assault life jackets support riders without restricting their movement for a day of uninhibited play on the water. Ample armholes and anatomical flex points grant roominess where you want and comfort when you need it most. Overlock stitched seams and fabric provide durability and a long-lasting life. With exclusive Nytrolite Polyethylene Foam Technology, these life jackets are more buoyant, 3x lighter and offer superior impact protection compared to traditional PVC foam. Nytrolite foam is also approximately 10% more buoyant than PVC, so less foam is required which reduces the bulk. Complemented by its lightweight, fluid foam neoprene shell, this vest will never weigh you down even during the wildest of rides!
