Soloing, the most dangerous form of climbing, just became a little easier thanks to world famous ropeless climber Alex Honnold. Along with Black Diamond, Honnold designed the HonnSolo 11, an airbag pack for freesoloing. The bag uses the same technology as an avalanche airbag, inflating at the push of a button, to create a landing pad. BD engineers tested numerous iterations of the device and found a way to deploy the airbag in mere seconds to enable Honnold to solo hard without care.
