What customers say about "Key Specs"
Kask Protone Helmet
  • The good - pretty damn great! Light weight, very comfortable.
  • All the design elements that Kask has put into this helmet make it feel like it is attached to your skull.
  • Fits nicely, no wind noise. I had a nasty crash, fractured my collarbone & hit me head pretty hard on the pavement but helmet protected me really well, didn't feel a thing.
  • My first one saved my noggin on a recent crash. Dented the helmet but my head didn't feel a thing. Replaced with the same one.
  • Lightweight and comfortable two of the biggest qualities I look for in a helmet.
Giro Synthe Bike Helmet
  • Really comfy helmet. Fits brilliantly and easily.
  • Breathes well and is very light weight.
  • It looks great and is reasonably comfortable.
  • Stylish looking, very well made.
  • Good quality, lightweight and comfortable.

What customers say about "Features"
Kask Protone Helmet
  • Very well ventilated even in 85 - 90 degree riding, and doesn't look like a mushroom! The rear neck strap adjusts for height, tightness, and even for the lateral positioning of the two cushion pads.
  • This is, without a doubt, the best fitting, best looking, lightest weight, and coolest helmet for road bike riding that I have ever owned.
  • Instead, the Protone fit provides full contact and, to me, that means improved safety and security.
  • Unlike my other helmets this one slips on and doesn't move. It fits my head perfectly, it's comfortable and it's looks like a million bucks.
  • Add in comfort from the best strapping system / materials I have ever seen, along with super ventilation, and I think you will get a sense of why I love this helmet so much.
Giro Synthe Bike Helmet
  • Look pretty good. Latest safety system.
  • Well made. Very good ventilation for hard riding.
  • Good price for the features and general quality.
  • Very light, easy to adjust, fits well.
  • Very comfortable helmet. The fit is easily adjusted, even to my fairly large head.
