I hate stuff in my pockets.
Phone, wallet, iPod + accessories, camera, chapstick, kleenex, gum/mints, pills, a pen, condoms, lotion, hand sanitzer, loot from the merch stand, sunglasses, saline spray, band-aids. I used to get made fun of, then my friends started asking "hey can I throw my keys in there" or "can I get some excedrin". Also, it's not a man purse or murse, it's an adventure sack.
