Great helmet for a great price

Familiarity:: I've put it through the wringer
Size Bought:: Large

I bought this helmet as an upgrade from my old Specialized helmet before MIPS had become known. The helmet is exactly what I ordered and compared to list price, Backcountry had a great deal on the product I wanted. I have ridden with this helmet probably close to 150 miles now and have crashed plenty of times. :-( Fortunately no skull crushers but the helmet has kept me confident and safe. This model lacks good ventilation IMO but that seems to be how these companies get you. You gotta buy the most expensive model to get the better airflow. The harness tightens up easy and the fit is good. Once it is on and tight it stays in place and rides well.

Chin strap too short

Familiarity:: I returned this product before using it
Size Bought:: Large

Fit great, plenty of adjustment for much larger head than mine (23 1/4") yet the I had the chin strap adjusted all the way out and if I leaned my head down a bit, like I might riding a bike, was too short and choked me. Other than that really liked and would have kept.
