I've owned a few Lazer helmets and always had great luck with them. For the price this is a bargain, great protection and Lazer quality. Just not the fit/feel of something like the Z1. ventilation is not lacking, it does a great job of letting your head breathe.

It's my second Lazer. I have one I wear on the MTB and it is lighter and cooler than my TLD helmet. This road going helmet is light enough and very reasonably priced. Runs true to size. I'm slightly over 58cm and the Large fit well with an adjustment made to the tabs on the inside of the helmet. Sunglasses and prescription glasses fit well.

Great helmet, I ride almost every day all year-round, and it's a very well ventilated and comfortable helmet. Replacement pads for the inside are very hard to find...I couldn't so opted for a universal pad type after the OEM pads wore out. At about the 2-year mark it started fading, the bright red helmet is almost white now. The only time it's exposed to sunlight is when I'm riding, so was kind of surprised, have never had a helmet fade on me. But, have to say it's a very good helmet, I suggest buying it in White :-)
