Using the Crest Jr youth helmet is easy. First, put the helmet on your head and use the Ergo Fit system to adjust it with one hand until it fits comfortably. Make sure the visor is in a good position to block sun or rain. When you're done using it, store it in a cool, dry place away from direct sunlight. Don't expose it to extreme temperatures or harsh chemicals. Regularly check the helmet for any signs of damage like cracks or loose parts. If you find any issues, it's time to replace the helmet. And always wear your helmet when cycling for your safety.
