Specialized Evade 4: Better Ventilation Without the Aero Penalty

Specialized's Evade 4 claims 2.4% better cooling without losing aero performance—a modest number that apparently translates to noticeable airflow at road speeds. The redesigned vents push more air across the front and mid-skull, which matters if you're stuck on a trainer or riding in heat. The fit system now uses a Boa FS2 dial for micro-adjustments, replacing the old ratchet mechanism. Mips and the same aero profile carry over.

Here's the catch: it's still an aero helmet, so don't expect Prevail-level breathability on long climbs in July. The improvements are relative—you're trading absolute ventilation for speed retention. If you're time-crunched and doing shorter, harder efforts where aero matters more than all-day comfort, this makes sense. If you're logging 4+ hour endurance rides in the heat, you might still want the Prevail. One practical win: it actually holds sunglasses without the arms digging into your temples. Pricing and weight weren't specified, but previous Evades sat around $275 and 270g, so expect similar.
