I've ridden this helmet on several long distance rides in moderately warm weather (high 80s). It's very well padded and seems to ventilate well enough that I just don't even think about it. I bought this after trying aero helmets from Scott, Giro and Oakley. This helmet is hands down more comfortable than the others. As for the aero benefits, all I can say is it feels faster than my traditional helmets. I don't own a wind tunnel...
Purchased black Utopia helmet and loved it so much I purchased same Utopia helmet in white to match wardrobes. It ventilates well while providing aerodynamic features. Cool looking is added bonus. This helmet has been around gor sometime but still best out there. Thx Kask.
Kask did an amazing job with the uptopia helmet. Great aero profile and styling. Performs great while providing the needed ventilation most aero helmets lack. One of my favorite aero helmets.
Very nice helmet. Looks great and feels high-end, with leather-type material covering chin strap, etc. My one complaint is that the strap hole over the ear is not adjustable. For me, this meant that it unfortunately would not work because it was too small and would dig into my ear lobe. Maybe my head is weird and it is not common ?????.
