The O2 XC helmet from Lazer combines crash protection, good looks and comfort to create the perfect fitting helmet that will protect you on every ride. The O2 comes to the table with the patented Lazer Rollsys retention system that uses a thumbwheel at the top of the helmet to adjust the fit of the helmet. Rbs or rigidity brace system reinforces the protective foam in the event of a multiple impact collision. The 24 vents on the Lazer O2 streams air into the internal ventilation channels for more comfort in warmer weather. The universal size fits heads up to 61cm and an oversized Lazer O2 XC for heads measuring 61-64cm.

Comments about Lazer O2 Helmet 2013:
I love this helmet. It is adjustable but it does seem to be on the big size. that being said, I have a smaller size M head and this is a one size fits all helmet so just keep that in mind.
