    Feels true to size

    Perfect fit, feels very aero.  Lightweight and doesn't feel too hot.  I've taken it out a couple of times on rides in 90+ degree heat and I don't notice too much of a difference between this helmet and a more aerated one.  Very satisfied with purchase.

    Feels too big

    The helmet felt a little larger than I expected. I normally would wear a Large helmet, but I had to tighten this to the max to get it to fit snuggly. Aside from that it is fantastic. I absolutely love and recommend this helmet. Definitely glad I bought and felt very fast when I raced this weekend with it.
