Clek Olli, Mammoth (Merino wool + TENCEL® Blend)

As a parent, you’ll appreciate that the Olli belt-positioning backless booster has earned industry awards. But we have an even tougher audience to please: 6 to 12-year-olds who won’t settle for ugly or uncool. With a carrying strap and a quick-release system, Olli gives kids the freedom to carry their own ride wherever they go – from your car to a taxi or even a plane.
