If I still have it on after riding, I leave it on. If it's really hot out and I am tired of the helmet, I take it off. My old trailer had ramps on either side and was about 2 feet off the ground. My new (used) trailer is about the same height. It either tilts or if I side load with ramps isn't so high that I'd be overly concerned with the X2 tipping backwards. There just isn't enough of an incline for the X2 or ATP to tip backwards without me having a couple of people in the boxes. So, the answer is no. IF I was putting it in the back of my pickup, I would always where one.

 

Helmets are a funny thing as far as sizes. I tried to put on my Sons 3XL it is a polaris one. By all the charts it should fit my melon No dice. Yet I measure by a 2X on most of those charts.

Usually you just need to try them...
