When you bought your pack, it may have had a loop (or two!) on the bottom to hold your ice axe(s), but… how do you attach the axe to your pack?
First, drop the ice axe down through the loop, so the head is above the loop and the shaft is through and below the loop with the pick side facing the middle of the pack.
Now fold it up and secure it to your pack using whatever the manufacturer put in line with the folded up shaft.
In fact, on Trails.com, they even have photos showing how to attach an axe to my exact pack!
Thanks, George, for showing me how, and for then posting the question up on BackClip.
