S. Leewrote a question about Black Diamond Vector Helmet on June 22, 2014
Whats the deal with the sizing? I currently wear a Petzl Elios which has a max size of 61cm, my head is roughly 62cm and the Petzl fits ok. Went to try the M/L (says it fits up to 63cm) BD Vector on and couldn't even begin to get my head in. I know manufacturers size things differently but this is ridiculous.
