I am very impressed with this Modular. I tour frequently and this Helmet offers me the best operation so far. 
 Fit: It fits as it should, and sizing is on par with the industry standard.
 Shield: Standard 3 position. However, the optics on the Rainbow Tint Shield are, in my opinion, High Def. Looks Cool!  Could use at night. Also changing/removal of the shield is easier than most.
 Inner Visor: The operation has no detent, there for smother operation from top to bottom. Holds its position well and fits easily over my prescription glasses. Optics also excellent.
Face Piece: Has a nice detent in the full up position and won't fall on its own. Also seems to handle the wind at high speeds when up.
Fogging: Has a moderate breath deflector that helps with fogging. Also, a chin curtain for keeping the elements out.
Buckle: The buckle is the new quick release style that is the new "Go To" type. Very adjustable and my favorite. 
Vents: Minor and seem to have minimal effect. 
Carry Bag: The bag is a step above most and comes with a drawstring. Very nice.
Conclusion: I would, and have, recommended this helmet to others. 
                 My New Favorite!!!
