Fit
This helmet fit well with or without a beanie hat underneath. The “K2 Dialed Fit System” is a simple dial on the back of the liner that adjusts a cable within the liner resulting in a very snug fit.

Vents
This helmet has a large vented area on the top of the helmet that is aerated through a series of eraser-tip sized holes as well as another set of vent holes on the brim and a set at the back of the neck. The vents are easy to open and close (even with gloves or mittens) and the small holes prevent any wind inside the helmet. Not a park helmet or great for warm spring days, but very good in my mid-winter test conditions.

Durability
K2 touts a “hybrid construction” of a lightweight hard shell and an inner molding. This does fine for common impacts with branches or snow but didn’t give me much confidence in the event of a head-on collision with a tree or rock. While I felt completely safe in the helmet, the shell feels a bit thin and doesn’t inspire confidence (despite the helmet meeting all technical safety requirements for the U.S. market).

Chin Strap
The chin strap adjusts easily and doesn’t loosen during use. I also appreciated the soft chin strap cover which prevents chafing but doesn’t get in the way of adjusting or securing/opening the strap.

Goggle Clip and Fit
The goggle clip is straightforward and functional without any snaps, making it easy to get goggles on or off the helmet with gloves on. Unfortunately, the brim did not fit well with some large-frame goggles or dome-shaped lenses.

Style
The brim on this helmet juts out just enough to be effective and stylish. I appreciate that the helmet is offered in a variety of colors and the color accents add to the décor of the helmet.

Extras
The included audio system is a very nice benefit of this helmet and allowed me to listen to tunes while still hearing sounds around me. This feature adds significant value to this helmet since not all helmets in this price range include audio.
