Coming from a cycling culture where it's the norm to wear a helmet, both as a kid and adult, and especieally in the fitness community (Road, CX, MTB), I'm having a question.
In the older days (5 years ago), there were two types of helmets. Road and MTB. Now it seems that the MTB have "branched" out. You can still get the "normal" lid for MTB, but seeing more and more of the back country style helmets (example Giro XAR vs Giro Fathom). Have the old type of MTB lid.... What is the prefferred type for people here in this forum, and why trail/backcountry specific helmets? Am I missing something here, what is the advantage the trail helmets?
(in other words looking for the excuse to solve the equation X-1, where X is the bike equipment I already have
