It's 1975 all over again and it doesn't get simpler than the Old Schooler. Sewn from a single length of seatbelt webbing, this padded gear sling is a simple and functional solution for racking extra pieces or racking gear to one side which I find especially helpful in dihedrals and chimneys.
Recommended Sizing: take a runner or some cord, sling it over your shoulder and pinch a loop. The last rib on your side is a good guide for where the loop should fall. You don't want the gear hanging off the to interfere with what's on your harness. Doff the loop and measure!
