I’ve been using the Giro Indicator and Giro Ionos for a few weeks now. At first I found the Ionos to be pricy, but ok. i didn’t think it was worth the €250 (Ionos) vs 50 (Indicator) though. (I got it at nearly half price at chainreactioncycles, so that was ok. ) I’ve been using the Ionos for two weeks non-stop and a few days ago I switched back to the Indicator because it was raining (the Ionos is NOT the best choice in rain as all the water neatly flows trough the vents down over your eyes) The Indicator does this much better with the front flap and closer fit. However, while biking I also found out that the Indicator was starting to feel sweaty and heavy after only a few miles, even though I really liked it before. It’s just that in day to day use, you get so used to the waight and coolness of the Ionos that other helmets don’t feel as nice anymore. I now definitely think it is worth the money.
