Fits small heads

I've put it through the wringer
Size Bought:
5' 6"

As a small woman I have trouble finding small enough helmets and this fits great with the 3 different attachment point options for the internal plastic web. Set in the smallest hole it fits me perfectly, plus great scores on the VA Tech helmet rating. This is my 3rd Troy Lee helmet!

Fits like a glove!

My favorite mtb helmet I've used so far. Fits my head like a glove (size MD, 56cm, round head). The retention system holds my head perfectly without creating any pressure points and the ventilation is great. Highly recommend!

So comfortable

I've used it several times

There are a lot of ways to adjust the fit, the padding is really nice, the ear straps are also adjustable, and the ventilation is excellent. Love it. My head always seems to be between sizes- it measures 56cm. I have room to spare in a size small.

Item pictured was not item delivered

I returned this product before using it

I ordered the XL/XXL Jet Gray which has blue straps. Helmet fit is perfect and well vented but not what I paid the premium price on this design to get one that is only similar.
