There's currently one company (in the US) that's making a "soft shell" helmet with D3O impact foam. Google D3O foam if you're not familiar with it.
By design this helmet almost ticks all of the boxes for an ideal kiteboarding helmet...
1. Good, snug and comfortable fit.
2. Close fit and close contour resulting in low drag without avoidable projections (e.g. fixed visors/bills).
3. Light weight.
4. Well padded with suitable material for impact absorption without creating excessive bulk and drag.
5. Good drainage/fit characteristics to reduce water retention and bucketing potential.
6. A good hard shell for impact dispersal and penetration resistance. Kevlar/high strength composites may offer better penetration resistance than ABS plastic.
7. Strong, corrosion resistant fastenings in an effective retention system.
Note: #6 is addressed by the D3O foam for impacts, but penetrations obviously would not be protected as well.
