5th jeans pocket. Do you use it? What do you have in it? The 5th pocket in your jeans is the small pocket within your front right pocket. I use mine to hold a couple different things depending on what i am carrying. Right now i have my bic lighter, modded LM Micra, and my Gerber Mini Paraframe. Normally i would have the lighter, bit extension driver for my LM Charge, and my modded LM Micra.
