The fit and adjustability are great. The boa system works great and is more comfortable than any helmet I have worn, though that is t many. Ventilation is also very good. Comes with a nice bag and an extra forehead pad, which is Oakleys is antimicrobial. All that is great. And the color (fog gray) and overall look are awesome. The one flaw is that whatever coating is on the helmet to create the matte color finish is pretty delicate. Not sure of this applies to the gloss colors but on mine it is very easy to scratch or rub off the matte gray. So mush so that I removed the size sticker and it left some adhesive on the helmet, but I’m too scared I’ll take the finish off if I try to remove it that I’ve just left it on there.

I purchased this helmet without trying it on beforehand in size LG. I own a LG Synthe helmet, but I wanted a 2nd helmet in white. My Synthe feels very roomy, but I do use a cycling cap every ride so that helped not make it loose. But I was contemplating on sizing down to MD, however I knew coming in the Aro3 was a slim fitting helmet, and boy was I not wrong. The helmet fits perfectly without a cycling cap on my head, but with one it is snug. I'll have to get used to it. Other than that the build quality is excellent and have no faults there. It does feel somewhat ventilated, although maybe not exactly as much as my Synthe. But you do get a lot of value for the price especially on sale. The aesthetics on head are a bit love it or hate it. Does have a slight mushroom look in the front, but if you like this style or don't mind a little of dorkiness than go for it. Kind of an alternative to poc styling. I'm currently satisfied with it.
