Great Helmet!

  • Familiarity:I've used it several times

Runs a bit small; I would order a size up. That being said, I didn't return mine. I have really enjoyed this helmet so far. It is very lightweight and comfortable. I wish the padding was slightly better, but the ventilation is great. My head never gets sweaty on rides up to 30 miles.
