STR (strength helmets) offers a complete range of open-face, flip-up and full-face helmets. They come in a number of colours to suit the rider's taste. They are made from polycarbonate which, thanks to the anti-UV property of the protective lacquer, shields the paint from sunlight — very useful over the summer months. The vents fitted to every STR helmet also form a ventilation system that improves how the rider feels, giving comfort and riding enjoyment. The hypoallergenic, removable, antibacterial cheek pads (the inner lining) are washable on every STR helmet available. Every STR helmet meets the required European Union (ECE) specifications.
