Runs large around head

I returned this product before using it

It's light, well made and has a great balance of protection and ventilation. I was right in the middle for the medium size and when I tried it on there was so much side to side and up and down play its unusable. Sadly they do not include extra pads or liners and the medium and large share the same shell so I could not size down without going to the small/xs shell. I returned this for a different brand.

Lightweight With A Snug Fit

I've used it once or twice and have initial impressions

This is my first full face helmet and am truly impress with the style, weight and fit. I like the look of he raw carbon and gloss black. The 3 way adjustment of the visor will allow goggles to placed on the forehead area. The weight of the helmet is amazing. It?s lighter than my half shell helmet and didn?t notice the weight when I wore the helmet. The helmet has a nice snug fit without added pressure. The replaceable cheek pads and helmet liner allows you to custom fit your helmet. I ordered a size medium and didn?t need to customize it. Overall the helmet is perfect for your first full face or as an upgrade. The SERT technology approaches head safety with an advance design. The 23 ventilations keeps you cool during longer rides or bombing downhill trails. You view is not impeded by the helmet.
