Two premium road helmets the WorldTour actually wears — Team Sky's Kask Protone Icon versus EF's POC Omne Air SPIN. Both ~160 g, both well-vented, but the rotational-impact tech and aero shape are very different.

Pick the Kask Protone Icon if pro-team aero credibility matters and you want the WG11 system that Kask has spent a decade refining — it's the helmet you see on the WorldTour podium most weekends. Pick the POC Omne Air SPIN if you want $80 off the Amazon price plus POC's signature high-visibility colorways — the SPIN silicone-pad system is a different but equally valid take on rotational protection.
POC Omne Air SPIN — $80 less on Amazon for nearly identical weight, ventilation, and certification.
Kask Protone Icon — 5 g lighter, 2 more vents, and the WG11 system has the most pro-peloton miles of any rotational tech.
