Bests & Worsts Reviews from Amazon

This is actually a very nice and comfortable helmet, if you can get the sizing issue worked out. It has a nice fleece padded liner and the circumference is easily adjustable using the wheel at the back. It can be adjusted while wearing the helmet, which makes it easy to get the perfect fit. The red color looks great, too... it is a shinier finish than expected based on the photo, but that is considered a plus by the 13 year old it was purchased for. As for the sizing, they are fine for both kids and adults (the large helmet actually fits me, too). It just depends on the size. It appears that the company lists this sizing: Adult/Youth Small (54-55cm [21.5"]), Medium (56-58cm [22"-23"]), Large (59-60cm [23"-23.5"]), XL (61cm [24"]) I found that it is not accurate, and you should plan to buy one size larger than would be indicated by this chart. I did actually measure prior to ordering, and with a head circumference of 57cm, I opted to buy a large (rather than medium as the chart suggests), and it fits perfectly. At the smallest setting it is a little too tight, and at the largest is slightly loose, so that is exactly what I would want for fit. Overall, I would definitely recommend this helmet, especially for the price. Just be sure to measure head circumference before ordering and then size up.
