Just an idea we've got with a friend while climbing the mont Blanc.
After a 12 minutes construction, my first prototype is ready to be tested!
cost: 0€, just needed a piece of tissu of paraglider, 6 lines, a scratch, and a few ideas.
weight: less than 50 grammes.
Therer will be probably a few things to change, but it seems to work.

Finally I will can reach the take off by running without the bag hurting my back at every step. And I accessory economize the wight of the bag, only 2.6 kg around my hips. Yeah!!!

and by the way, Tyrol songs rules :o)
