I own a bunch of backpacks and everyone of them has a Fifi hook looped onto the handle. I can't stress how handy it is to hang your backpack anywhere,,, really, anywhere! a branch, a chainlink fence, a crack in a big rock. really put a fifi on your pack and you'll never have to drop it on the wet ground again, even in the office you still be able to hang it somewhere instead of throwing it on the floor. Hey Black diamond designers,,, give a fifi hook with every pack you sell and give your customers one more reason to buy the best backpacks on the market and something no other companies have thought of or even offer,,, and if they do purchase another brand they'll still buy a fifi hook from BD to make they backpack complete. I use these to hang many things, they truely have hundreds of uses!
