Purchased this helmet to replace an older Giro of a couple years old. Fit feels great, the thumb wheel in the back is easier then my older one. Wore it for the first time today in all this heat and humidity and the ventilation seemed to be fine. So damn hot it's hard to tell.I like the way the helmet looks and fits and the MIPS system should make it very safe. The vendor chose a shipping method that took 20 days for the helmet to be delivered. I'll find another vendor for any other bike related purchases.Very light and comfortable helmet but would be best designed for the price. The regular price is $200…doesn’t worth. Taken it on sale for 150….Better stylish helmet available on market at the same price…for me it’s overpriced…decided for this because of the branch. Just work as it should.Replaced an old Giro. 10 years of helmet development shows.Was looking for an upgrade for my rode helmet and could not find one At the level I needed and was pleased with arrival of product in 24 hrsA COMPANY YOU CAN TRUST!!
