If you're lucky enough to be outside, you'll have the sun shining brightly down upon you. Now touch the top of your head. Yes, this susceptible portion of your body is being constantly berated by that sun above. Over time, this could lead to some issues, which is why we developed our Deflect™ UV Cycling Cap. It's not a substitution for sunscreen, per say, but it will help combat the harmful effects of ultraviolet rays.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.
