Technology that saves lives. Of course, it’s fantastic what’s possible these days, thanks in part to Apple Watch and BMW SOS, among others.

THE HDSL

It is a shame, however, that these are all extremely expensive solutions, which means that they are unfortunately not available to everyone.

CASTODIAN has teamed up with a number of partners to develop the HDSL: a small, affordable helmet solution that can save the helmet user’s life in the event of an accident.

Be patient, help is on its way!
