From Kokatat "Our most comfortable life vest ever thanks to soft, Gaia PVC-free foam that's cut and sculpted into body-mapped, floating panels. Each foam panel is precisely slit to provide adaptable and ergonomic fit, wrapping the torso in secure comfort. A soft 100D stretch polyester envelope finishes off this high-back recreational life vest, with fleece-lined hand warmer pockets for the colder days. This Life Vest is certified for use in both the US (by The US Coast Guard) and Canada (by Transport Canada). You do not need to select a certification. The life vest is dual certified for both countries."
