After many helmets that wobbled back and forth on my head, this helmet has a racketing device in the headliner to tighten up the fit. It stays where I put it and protects my head. 5 stars

I didn't have great confidence in the "universal fit" system - until I tried it. I have owned higher end helmets from Bell and Giro, and this fits as well as any I've owned. I can't see spending $100 for a helmet when this Bell does as well for a third of that. 5 stars

I was skeptical of the one-size fits all, as these rarely fit me, but I am happy to say the helmet fits fine on my 7 7/8 hat size head. It is just a tiny bit snug, but does the job. The price was right at twenty bucks for my blue and white helmet.

The build quality is excellent (better than my Giro Mojave that was falling apart). I hope to never have to use it, but it should hold up well. It is comfortable for my 11 mile bike ride. 5 stars

Purchased the Bell Solar Bike Helmet and it fit comfortably. Easy to adjust once I figured out how the straps worked. Recommend this product and company to anyone interested in buying a good reasonably priced helmet. 5 stars

I have a large head. I was a little skeptical about the universal fit, but it does adjust so that it can fit most heads. For my head, I would prefer that the helmet was just a bit larger (the helmet is the constraint, not the adjustable inside). But, while at times it seems bit tight, I've decided to keep it as the alternatives seem to cost twice as much. 4 stars
