SixSixOne 661 Evo AM MIPS 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.
MIPS
The most common type of impact that occurs during a crash is an angular impact. During an angular impact, a rider’s brain is subjected to strains caused by rotational acceleration. MIPS (Multidirectional Impact Protection System) is a thin liner placed inside the helmet between the shell and the comfort liner. This liner acts similarly to the fluid in your skull and works to reduce the acceleration of your brain.
Key Features:
- In-molded construction with 15 oversized vents
- MIPS (Multi-directional Impact Protection System) integration
- Made with Contego EPS, an EPS that can substantially reduce impact forces vs. standard EPS
- Micro-adjustable fit with Boa 360º
- Lowered back of shell offers additional coverage
- Three independent shell sizes
- Liner made with Drylex antimicrobial material
- Fidlock magnetic closure system
Occasionally, without notice, manufacturers change product design and/or specifications.

How to measure yourself for a helmet
To find the circumference of your head, place a tape measure in the centre of your forehead, wrap it around above your ears and around the back of your head. If there's a slight difference between two different sizes, always go for the tighter size.

---|---|---|
XS | 53-54 | 20.86-21.25 |
