This helmet performs admirably at this price point. If you're riding once or twice a week, this helmet will definitely suit your needs. The adjustment is simple and wide-ranging so that it will fit most noggins. It's lightweight but still feels substantial enough to protect your dome. The straps are sort of annoying in that sometimes they will twist up around the ear, but as an entry-level helmet, you really can't ask for better.

Good value, light weight

This helmut is comfortable and fits well especially with the choice of sizes instead of one size fits all. Make sure you measure your head to select the proper size. Good value for a mountain bike helmut that I also use from road biking and has all the features I really need. Sunglasses fit well with helmut on. Adjustment in back works well. Only slight drawback is that the visor is not adjustable such that it can be pulled down to block the sun near dawn and dusk.
