Peter Gwrote a review of Giro Air Attack Shield Helmet on September 10, 2015
Familiarity: I've put it through the wringer
I don't find the tighten/loosen adjuster too small as another reviewer did. This helmet is surprisingly cool and definitely efficient too. The built in lens is easy to remove while riding.
However, the built in lens also takes a little getting used to. On my first ride I had an itch on my nose and when I scratched it I pushed the lens off and it landed on the road behind me; had to pull a "u-ee" to pick it up;fFortunately I was riding solo and no damage was done. I've sinced learned my lesson.
Fits me nicely too (as Giros have in the past).
