Now, it's important to note that we didn't make this cap out of tinfoil, meaning that it's not a cure-all bit of snake oil. It does, however, serve up a UV 50+ level of protection, which is more than your hair or helmet are offering. Add to this the obvious benefit of the fine-as-silk VaporRize™ fabric blocking sweat from trickling down into your eyes, plus the fact that this lightweight material does is actually remarkably cooling, and you're looking at a smart solution to your summer riding. Stay protected, stay seen.
