The Dainese® Jet Stream Tourer Basic is the ideal helmet for teens moving in city traffic. The external shell in two sizes allows a perfect fit. The ventilation system cut into the edge of the visor, the removable and washable liners, the housing for the goggle temples, the visor removal without tools and the fastening system with micrometric adjustment ensure high comfort and ease of use. Thanks to the burglarproof lock ring you can leave the helmet on the scooter safely, with no need to always have it with you when walking around.
