[Bicycle Helmet Safety Standards] US/Canada: CPSC, 16 CFR 1307, 16 CFR 1203: safety standard for bicycle helmets. Europe: BS EN 1078:2012+A1:2012. Recommended age range: 10 years and up. Recommended head circumference: 57-62cm. [High Impact Resistance & Lightweight] Shinmax bicycle helmets are designed for adults, but the adjustable size makes them suitable for children. The exterior is made of sturdy PC material, while the interior is made of highly impact-absorbing EPS material to protect the rider's head. While ensuring safety, the lightweight construction makes it comfortable to wear. [Bicycle Helmet with Tail Light] The tail light provides safety at night, with three modes (flashing, fast flashing, and steady on) for increased visibility and safety on dark roads. Easy-to-replace batteries (one pre-installed, one spare, or two included) make night cycling safer. [Magnetic Goggles - Glasses Compatible] These road bike helmet goggles come with dedicated magnetic goggles, made of thin polycarbonate material for a more natural and clear view. These road bike helmet goggles protect your eyes from the sun and insects, preventing discomfort and ensuring visibility. They can be easily put on and taken off with one hand. While these are glasses compatible, please note that they may not fit some glasses depending on their shape. [Insect Protection Net & Dial Adjuster] An insect protection net is essential for road bike helmets. When riding along rivers and other areas, you can ride without worrying about flying insects. The dial adjuster at the back of the helmet can be tightened by turning the dial, providing a snug fit around the back of the head for safety. [Excellent breathability] A casual shield-style bicycle helmet with a cool look. The aerodynamically designed ventilation holes allow air to pass through easily. Scientific analysis based on wind tunnel experiments has significantly improved the breathability inside the helmet at low speeds, effectively reducing air resistance and efficiently expelling hot air from inside the helmet, making you feel more comfortable.
