I takes time for new goggles to be tested and approved by the ASTM, I doubt with a company as driven as HK that they will never make the market, but they may be delayed as prototypes are tested and re-submitted as necessary before going in to full production.Don't bother with the HK ones, been delayed by 2 months again and no doubt will continue and never arrive on our shores.
@fraaaaanka The FS come with an excellent lens and if they fit you well you'll be happy with them.
