I love the 'sink-fit'... also looks great compared to the goofy, alien-look of the typical bike helmet.
I also love the fact that I can also use this in the winter for snowboarding. In fact, mine came with the snow liner (I believe, w/ the Bern Brentwood model, you have to purchase the winter liner separately). It even has sliding vents to keep the snow out & the warmth in.
My teen son actually like the helmet, so I bought him a G2 as well.. & you know how it is trying to get teens to wear a helmet!
