Is the Formula CP Seal good for motocross?

Yes. It is a purpose-built motocross helmet with a peak, chin-bar venting and a dual-density EPS liner. It suits track and trail riding rather than street use.

How does it compare with the carbon Formula helmets?

The CP Seal uses a polycarbonate shell, so it is heavier and less expensive than Fly's carbon Formula models. It keeps the same general shape and vent layout but gives up some weight savings.

Does the liner come out for washing?

Yes. The comfort liner is removable and washable, which owners say makes cleaning after muddy rides easy.

What sizes does it come in?

It is offered in Large and XL. Fly recommends measuring your head and checking its size chart, since fit varies between helmet brands.

Is it compatible with goggles and neck braces?

The eyeport is sized for standard motocross goggles. Neck brace compatibility depends on the brace maker, so check with the brace manufacturer before relying on it.
