I've had an FS-15 for over a year now (matte black, for visibility), so I'll chime in.
Cons (because sometimes they aggravate me):
- No antifog faceshield
- Poor faceshield detents, the lowest one is worn out, making defogging at a stop problematic (clears quickly once moving again)
- D-ring strap often binds, preventing a full tightening, still haven't completely figured out what's causing it
- Front mesh vents suck in the winter, as they can't be closed
Pros:
- Lighter than my old Scorpion 700
- Quieter than my old Scorpion
- Easy faceshield swap
- Economical
- Decent venting
It was one of WebBikeWorld's top helmets in 2009, which led to my purchasing it. $80 is an AMAZING deal. After all, YOU don't have to look at the graphics if it's on your own head.
