I've got a few rides in with this helmet and so far it's been great. I typically have to wear a l/xl helmet but with the Giro sizing I was able to fit into a medium which makes for a more compact and better fitting helmet. Ventilation is great and it's very light weight, hardly notice it once it's on. The fit system of this helmet is highly adjustable so you can really dial it in. It takes some time to get it right, but once it's done you shouldn't have to mess with it again. My only complaint is the height adjustment on the RocLoc moves up and down too easily. I usually reposition it once the helmet is on and then adjust the RocLoc as needed. If I crash and burn and need to replace this helmet I'd get another Hex.
