SixSixOne 661 Evo AM MTB Cycling Helmet

We chose the best fit system on the planet, the BOA FS360. The original leader in fit, micro-adjustability and customization to be sure our helmet fit was the best on the market. With a lifetime warranty on the entire BOA System you are “Dialled In For Life”. In place of standard EPS foam liners we substituted Contego EPS Foam. Contego Foam is superior to EPS foam with far greater impact absorption. In laboratory testing Contego has been shown to decrease energy transmitted during an impact.

Key Features:

• Contego EPS material
• Fidlock closure system
• Light and well-ventilated design through in-molded construction with 15 vents
• Secure and micro-adjustable with the 360˙ Boa®
• Fit System
• Additional protection through extended rear shell coverage
• Precise fit for all with 3 shell sizes
• Plush interior liner made with antimicrobial fabric

Occasionally, without notice, manufacturers change product design and/or specifications.
