Quantified cooling.

In the past, choosing a helmet often came down to a dichotomous choice of aerodynamics or ventilation, speed or comfort. Nowadays, options such as the MET Estro Helmet let you choose both. Featuring large vents and a streamlined design, this helmet is simultaneously fast and cool.

To achieve this, MET didn't just aimlessly add air ports into the Estro's design. Instead, it developed a protocol that measures a helmets performance in terms of ventilation called Air Scale. Simply put, it measures two essential parameters -- the Head Contact Surface (HCS) and Cooling Factor (CF). The HSC indicates, with a percentage, how much of the head is in contact with the helmet. This lets MET design the HSC so it's at a minimum, in this case 65%. This helps the Estro decrease heat buildup and gives it a Cooling Factor of 7.5 out of ten.

A Safe-T Smart retention system holds the Estro snugly in place using a micro retention system that features both horizontal and vertical adjustment. This easy-to-adjust system distributes pressure across a broader surface than other retention systems to increase comfort. Inside, MET's Cocoon internal padding offers a soft and protective layer against your skin.
