The Bolle Millennium is a ski and snowboard hemet that uses a hybrid shell construction for optimal protection and has a fur inner lining. 

Comfort
The Bolle Millennium did not fit true-to-size for some testers and thus created pressure points. For testers that it did fit, the fit system felt secure and comfortable throughout the entire day, though the fur liner was irritating when it shifted out of place.

Weight
Although the Bolle fell into the mid-range for weight, it felt quite clunky and heavy due to size and shape. Head movement was hindered slightly and the helmet felt loose at times. 

Breathability
The Bolle Millennium has two vents in the front for air circulation, and six easily adjustable vents on the top. The lining is fully removable, as are the ear pads. No wind came through the ear pads or front of helmet, but testers still felt cool all day long. 

Ease of Use
The chin strap was easy to adjust, as was the goggle strap. The fit system dial was also easy to use, even with gloves on. The magnetic buckle system was easy to release one-handed. A variety of goggles fit well with no gap.

Features
The helmet has a goggle holder and is audio compatible. The Bolle Millennium uses a hybrid construction with the outer shell protecting from impact while maintaining a lightweight and comfortable fit for the lower portion.
