Got myself a Shark Evo-One2 recently, to replace my very old Shoei Multitec.
Both XS - whilst the Shoei has more room internally (Shark has a tighter fit), the Shark comes out a bit wider externally.
Loving the Shark so far - at 60mph on my naked bike, it's more stable and doesn't try to lift off my head.
Visibility - night and day difference, with the Shark providing a nice wide viewing angle despite having a pinlock anti-fog screen fitted. Internal sun visor is great - no longer need to put sunglasses on underneath.
Noise - the Shoei has a lot of very low pitched noise (ear plugs can only do so much). Shark has far less low pitched noise, and instead has high pitch wind noise which is easier for ear plugs to attenuate.
The Shark is quite an airy helmet around the face/eyes - not tried the chin curtain yet, which will probably reduce that.
Quite pleased over all - and being an XS wearer, there are always clearance deals as it's not a common size that sells quickly. Got it for £150.
