I made it two years ago, after not being able to find any similar product in the market: Minimal and with full protection on 360º.
This two years I have hiked with it more than 2500km in several trips (Pyrenees High Route, Cordillera Cantabrica High Route, The Alps from Switzerland to the sea...), with very good performance on them.
Now, I am planning to make another identical or similar one.
I have some more photos and info on my blog: http://mikel-salazar.blogspot.com/
