Great product.
This is by far the best off road helmet I’ve ever owned. Chanced an online fitmenr decided to size up and made the perfect choice. If you can’t try one on you may want to go one size bigger than normal

Get one size up.
Comfortable, light, good airflow. I've been riding for 20 years and gone through more helmets than I can count. I've always been an XL with zero exceptions regardless of the brand, but for this one I had to size up to XXL and it's not even close to being too big.
