Customer Reviews for Arai Quantum - Leon Grey

November 28, 2012

Great product, as ever!

This is my fourth Arai lid of this level (have had 2 RX's too) and it is still a very high quality product. I haven't used it a great deal yet, but it is comfortable and well made with the usual good features.
