Pros: comfortable, highly adjustable, warm, vented, lightweight, stylish
Cons: slight goggle slippage
Fantastic helmet. Very lightweight, extremely comfortable and adjustable to fit just about any melon out there, fully adjustable venting, and very stylish. You won't look like a bowling ball in this thing! One nice subtle, but important, thing is there is little wind noise into the earflaps when moving at higher speeds on the slopes. Some helmets are brutal with wind noise. There's a little rubberized "deflector" at the leading edge of the earflaps; obviously Giro did their aerodynamics homework.
My ONLY criticism is due to the shape of the front part of the helmet where it meets the brim, goggles that are pulled off your face and sitting on the brim are slightly prone to slipping a bit. Even with the grippy surface on the inside of the goggle strap, they tend to slide back unless you position the goggles right against the brim. Not a big deal at all, just a very minor thing to keep in mind. Other than that, excellent helmet!
And look around for clearance sales, there are some phenomenal deals on the Seam.
