Designed as a “complete performance helmet”, the 2011 Specialized Prevail bicycle helmet (shown in here in Omega Pharma-Lotto color scheme) mixes lightweight, big vents and comfort with aerodynamics. It has 25 vents (29 if you count the little reinforcements in the rear slots) molded into the dual density EPS foam.
The shell is molded around an inner matrix to keep it from breaking apart in a wreck, and their Pro Fit 360 system wraps around your head for a secure fit. Specialized’s Mindset retention system offers 24mm of vertical occipital lobe adjustment and uses a double-clutch ratchet dial that tightens or loosens to customize the fit (photos after the break). A brow pad covers the entire forehead, which Specialized says lets you make the helmet snug without causing any discomfort.
With a claimed weight of just 185g, it’s clear the Prevail is gunning for Giro’s ProLight helmet (which we reviewed here), but seems to add a lot of adjustability and an emphasis on aerodynamics. In their testing, the Prevail recorded 1082g of drag, the lowest of the helmets tested.

Inner Matrix webbing keeps it together in a crash.
The minimalist Mindset retention system shaves grams while still allowing fit customization.
Not shown in these pictures is the fixed webbing. Like the Giro Prolight, the Prevail has straps that are fixed in position, but you can adjust the chinstrap part.
