Mountain Airbag
I have been living in Italy for the past 25 years and a mountain guide for 10 years and have seen a lot of people doing reasonable things in the mountains, that suddenly went bad. Something that would protect your neck and head would certainly help. A close friend was killed, just tumbling down a completely grassy slope when he tripped on an exposed root. Unfortunately many stupid people will probably think that this device makes them bullet proof.
I have a small book of Latin sayings, translated into Italian.
" In love, destiny usually forgives you two errors - in war, destiny usually forgives one error - in the mountains your first error is likely to be your last error."
So "heads up" and be careful, even if you have a flak vest. Avalanches are best avoided. Don't be confused by the terms "objective" and "route", the objective is not a geographic point. The objective is to return, route is a secondary consideration.
Best regards.
