This is one of the most comfortable helmets I have ever owned. Its an Alpine Stars product and that alone says it all!!!
My measurements are at the top end of the small range so I Bought the small. when I got it there was no doubt it was way too small. Sent it back, sized up to a medium and I can say this is one of the best helmets I’ve owned. It’s very light.
By far the lightest and most comfortable helmet iv owned!
Killer lid for my little one. She picked it and did a good job. It fits great, looks great and is a awesome helmet.
I bought it in the winter so I haven’t worn it for a day of riding yet but although it is nice and light,The liner is very thin. I have a pressure point at the top of my head. It is not as comfortable as I would have expected for almost $400 after taxes. The chin strap also sits awkwardly close to my neck. My 100% race craft goggles do not fit in the helmet because the face guard is very close.Unfortunately there is nowhere to try one on so I took my chances buying online.Although it is true sizing.
Love this helmet! So light and super breathable. Great purchase
Very impressed with the sm5 i received from bikebiz.com. The fitment was perfect and the delivery time was also very good. i will be using them again fir sure.
