The specifications are quoted from Amazon below: =========================== Bicycle - SG Standard Certified Product Brand: KABUTO Color: Beige Target Age: Adult Size: 54cm~57cm Lightweight and compact internal design. Weight: 315g Reflective material for safety at night Hat-like shape for a natural look =========================== Purchased on Amazon in October 2023. It is a genuine KABUTO product. It is SG mark certified and very well-made. I purchased the smallest size for adults, but it didn't quite fit me, so I only tried it on and stored it in the entryway. I kept it because of its design, fabric, and color, but I am selling it because I purchased another helmet. Thank you for reading this far. Thank you.
