Rudy Project's offering of the Egos in three sizes (small, medium, large instead of small/medium or large) was a big draw. Historically, I've worn the small/medium sized helmets from Rudy Project and experienced just the slightest bits of wiggle in all but the Nytron; the updated retention system was a brilliant addition. Because the Spectrum in a medium I had been sporting the past couple of years was a spot-on fit, I decided on an Egos in white, rather than a second Nytron that would be used exclusively for road riding. While the Egos is not the most svelte helmet Rudy Project has produced, it is certainly a technical marvel. Its numerous vents make for the Goldilocks of comfort & air circulation: It's just right no matter how hot or how cool out it is. (FWIW, the Nytron also stays remarkably cool, even in South Texas summers, even in the black color scheme.) The Egos's new magnetic buckle system supplants the tried, true, but tired traditional buckle system used on most every other helmet system out there; it connects & disconnects quickly, conveniently, and securely. Apart from its more bulbous shape (the half-sphere at helmet's top sits a bit higher/larger than the Spectrum, Nytron, and other current helmets on the market but falls short of Space Balls proportions), the only "down side" I've experienced with the Egos is stashing glasses in the vents. It's not as intuitively easy to slide your shades but can be done with a bit of practice; Tralyx, Keyblade, and Rydons all work well enough in my experience these past few weeks.
TLDR, the Egos is a well-ventilated and comfortable helmet for all your road bike adventures making it figuratively & literally Rudy Project's most technically cool helmet offering to-date.
