Reevu's MSX1 helmet has been around in one form or another for years now, but the company has apparently be busily working on improving it all this time, and it's now finally let an actual production unit loose for an early review. As before, the helmet relies on an entirely mechanical mechanism rather than rear-view cameras, which webBikeworld says ends up functioning much like a car's rear-view mirror in practise, with the small mirror in front resting just outside the rider's line of sight. Most importantly, however, the site says that the helmet itself is "built like a tank," and is "good enough to stand on its own even if it didn't have the rear view system." Head on past the break for a quick video overview, and hit up the source link below for the site's complete review.
