If you are serious about trees. And having side protection on your head, then there is only one thing you will say when you get this helmet.. why the f did I wait so long. Same with the sena if you haven't got it yet.... 5 stars!!! Mine has speakers intercom I can call ppl. Hands free. It's got vents for when it hot. I went ahead and got the built in glasses. A MUST with muffs. You don't want the glasses over you ear with the muffs. I would just buy the adapter and use your shades.
