A friend of mine bought the EVS one.
His opinion after the first weekend is it's crap.
Chafes his neck, Have to pull the helmet off to remove, The padding is glued on & was coming apart after only one weekend.
Limitations were not much of an issue. More or less forgot it was there until he tucked for high speed sections.
He recommends going for the Leatt. Much better & higher quality.
He kicks himself now for getting the EVS.
