Thank you for viewing! This is a helmet I purchased on Amazon. The product name on Amazon was as follows: ------------------------------------ OUTDOORMASTER Bicycle Helmet Sports CPSC Safety Standard ASTM Safety Standard for Children and Adults ------------------------------------ It's a size M, for head sizes 52-58 cm. The size is adjustable. Suitable for both children and adults. Images 7-12 are from the Amazon product page. It seems the black color is no longer available. I bought two colors for a sport I was just starting, but I only used the other color and kept this one in storage. After that, I bought a helmet specifically for that sport, so this one has only been tried on. There are some minor scratches from being stored at home, so please purchase only if you understand this.
