The Salus Nimbus makes water play safer for children and more relaxing for adults. All PFD's float but they can't save lives if children won't keep them on. Designed for comfort and soft to the touch, the Nimbus encourages children to wear it for hours at a time. Specially contoured to hug little bodies, children will get the best fit, mobility and safety at the water's edge, while swimming, or boating.
