what size is this helmet?

This is a youth helmet. The youth size fits 8+ and a head circumference of 19.5" to 22". Thanks!

Does this have any kind of adjustable harness inside the helmet?

It does not have a harness but it’s a well built adjustable helmet

Can you use this helmet to ski?

No, this is not a ski/snowboard helmet and is not recommended. Source: ski & snowboard instructor.

Does it fit for typical 14 years old boys?

In my opinion, unless your child is small, an adult sized helmet may fit a teenager better than a youth sized one. This fits my 7 year old.
