Have had a Flux for some time and more recently a Feature. They are both very good the Flux I think is a little more luxurious and probably a little more trail-tastic whereas the Feature is a bit basic like a rally car but the coverage is better and imo it looks more gnar.
The Feature is well thought-out and is unobtrusively light for a helmet of this type. There’s not a lot of the interior in contact with the head so it makes good use the fairly basic ventilation. The only negative is the chin straps are cheap verging on nasty and don’t have under-ear adjusters which could be a problem if your ears aren’t where Giro think they ought to be
I wear the Flux for sociable trail riding and the Feature when I’m ‘on fire’ 🙂
