For my head, the best half cut fit ever! Better than any XC or Road helmet I?ve used. Of course a bit heavier than the lightest XC and Road helmets I?ve used but way better fit. I like the full face from TLD a lot as well, so it might just be my skull-shape. Very balanced, do not move at all (even on shaky paths), very good cover of back head (upper neck) and surprisingly airy. Do not feel to warm. Cool design ? I guess TLD half cut is beck, just better? Just love it. My reference brands used the last 10 years: Half cut: Bell, Giro, Met, Catlike and Sweet. Full face: Bell, Giro, Troy Lee d. All of them ?top of the line? models.
