Tough as nails, light as a feather.

Six Six One built the Evolution Helmet with a blend of carbon fiber and fiberglass to make it incredibly light and still maintain all the strength it needs to keep your head protected. This full-face lid packs both ASTMS and CPSC certifications, not to mention a flow-through venting system that keeps you noggin cool while you ride or race. Six Six One even throws in a crash-replacement policy, so if you do wreck bad enough to split this thing, you get a new one.

I LOVE this lid

This Helmet fits great; I don’t even notice I am wearing it. Everything about it is awesome except the purple accents could be a darker shade.

I LOVE this lid

Buy it! Great deal!

Ok it Works! Landed head first OTB's on fast downhill in Mammoth. Only a few scratches on surface of helmet. Flexible visor didn't even break. This helmet is super light with great protection! It has great visability also. Recommended it to a friend who bought it and also likes it.

This helmet is AWESOME, the ventilation is pretty good, but the main thing about this is the price, and the fact that it weighs like nothing. When you wear it on your head, or when you are carrying it around, it does not feel like you have a full face mask, it just weighs probably as much as a regular half helmet, or feels like it to me. GET IT if you have the money, there is no other choice, a $300 helmet for $175, that's a bargain if i have ever heard of one!

Beautiful piece of work!!

This a VERY slick and sexy helmet! Not too crazy on the graphics, but still looks like a great and stylish helmet. My head measures 57 cm and the large fits nice and snug. Has really good side vision! SUPER LIGHT! I weighed mine on a Park Tools table scale and it came in at 965 grams!! Thanks for the awesome deal on it Chainlove!
