Giro Aeon Helmet is the goods, but the Roc Loc 5 is not...
Giro Aeon Helmet is a good to go helmet, light and breathable. No stuffy IGLOO on your head with this DADDY. My only issue is with the the Roc Loc 5, which secures the helmet at the back of the top of your neck. I am on my 3rd one now and I have barley had this helmet for 9 months. That is under warranty form GIRO, but it is a pain replacing them. Never had a problem with the Roc Loc 4. If GIRO fine tuned the Roc Loc 5, this would be the only helmet on my head. A good friend of mine has the exact same problem with his Roc Loc 5, so that chisels away at the user error issue. I hope that GIRO improves the Roc Loc 5 for 2012, or maybe I will be back to wearing IGLOO's again. Then again, all my beer will get warm... no we can't have that.
