where’s the size chart & measurement instructions in the product description???

Hello, thanks for your question! We have tried multiple times to add a size chart, but Amazon will not allow us to add information. In place of that, we will answer your question here. You should measure your head around the crown with a soft measuring tape or use a piece of string then measure the string afterwards. The sizes are as follows: Small: 51-55cm Medium: 55-59cm Large: 59-62cm X-Large: 61-65cm Thank you! The Flying Kiwi Outdoors - Authorized Smith Optics Dealers

Are there any plans to have any color other than black available in the XL size? Was hoping for something with higher visibility.

I'm sorry to say that Smith only makes XL in black, which is too bad because we do get people interested in the larger sizes in other colors.

Is there a light the clips into the back of the helmet?

No. At least there isn't one included with the helmet.
