Specialized Deviant review
The Deviant is covered in vents so a sweaty head won’t be a problem, plus the liner is removable.
It’s one of the few full-face helmets to have a D-ring fastening buckle and also has a directly adjustable band (Pro Fit 2 system) at the rear.
The adjustable headband helps you get a great fit dialled but is tricky to adjust on your head and the jaw looks a bit long, although vision isn’t affected.
This helmet is light and would be best suited to freeride duties.
