I put my lighter and guitar picks there. I sometimes put my ring in there, too. And flash disks, memory cards... Wow, I just realized I use that section for real.
Not the small pocket on jeans, but I do have some pants and shorts that have a small pocket fully inside the other pocket that I like to put my keys in
Keeps them from rattling around and scratching things
My biggest test for wireless earbuds is if the case is small enough to fit in that pocket. The usefulness of that is incredible, it's like they're not there.
God i loved that thing. Simple and effective. Easy to use for sports or just hanging out.
Im sad mine isint working anymore, i tried reviving it but alas, it's light never blazed again.
I use it for a small pocket knife I always carry with me.
Also fits a vape, a lighter, your house key (when you want to go out with nothing else on you), a couple guitar picks, or a few coins if you use one of those fancy new wallets that only hold cards and bills.
In my younger days of hitting the club, I would use it every time I went out. Wallet in right back pocket, lip gloss in small pocket.
I never use it now. Now it's wallet in left back pocket, phone in right back pocket, keys in right front pocket, earbuds in left front pocket. If I'm working and wearing cargo pants, work gloves go in left back pocket and wallet shifts to a more secure left leg pocket, pens and box cutter in right leg pocket.
I keep quarters there; Iike to shoot pool in bars. Also my wedding ring when I take it off to wash my hands, cook, or do other work I don't want to wear it for.
I used it for my earbuds case for a long time. I don't buy many pairs of jeans and wore the same pair for most of the pan (I didn't leave home for more than a couple hours of walking and listening to podcasts most days, so they only got washed sporadically). It eventually wore through and frayed. I'll probably resume that usage when it gets warm enough not to carry a hoodie.
Sometimes I'll toss a Zippo lighter in there if I'm going out drinking or something. Otherwise, it's unused. My pockets only have my wallet (which has its own change purse), my phone, and a handkerchief (living in hot and humid areas means lots of sweat wiping). Keys get clipped to a belt loop. I'm generally not carrying anything else and it will likely end up in a bag of some sort if I am (especially when I lived down in Tokyo and was away from home generally unless sleeping and was taking public transit).
I used to only use it for random change I'd get on the rare occasion I'd pay for something with cash. Nowadays it's always filled with dog treats since my dog is nearly always with me.
