Why do jackets suddenly have pockets in the sleeves?

[Lord of the Large Pants]

When did this happen? What am I even supposed to put in there?

 

[Something Awful]

Emergency rations (beef jerky).

 

[AbduluCthuluZulu]

They're for hiding knives in, Assassins Creed-style.
Or a really tiny pistol like a derringer if you're feeling quirky.

 

[Rent Tin]

Seems dumb to me, I can't think of a time when I want stuff actively hampering my arms. Stuff goes around the waist or secured to the torso.

 

[$80 Nude Haircut]

Trickle-down from military designs that had them for years.

 

[Behavioral Sink]

Bus pass. Kleenex. Lighter. Chapstick. Anything bulkier than one of those items, and it's in the way.

 

[The Magnificence]

It's TACTICOOL ya fuckin' cupcake! Ya put yer AMMO in there! What are you some kinda pinko commie librul?

 

[Agent Abe Caprine]

You're supposed to cosplay Altair.

 

[Uncle Sid]

Vagina envy.

 

[OrionBalls]

You can put your weed in there.

 

[Sexual Chocolate]

You can put your weed in there.

Or those party pens

 

[Beak Thing]

Seems kind of redundant unless you have very short arms or a very large inventory.

 

[Kamen Rider Faiz]

I have one of those
At first it seems like the perfect place to keep your phone or mp3 player whenever you're listening to music or some shit with your earphones
Too bad mine is too big to fit in the pocket, I miss my mp3 player, small and comfy to use
might work to hide candy there too

 

[OrionBalls]

Or those party pens

We don't fuck with party pens since Jayna died. Dealers don't care if you live or die, anymore. The solution is to gat yo dealer and steal his shit.

 

[D_Tractor]

Top Gun Maverick. US Navy flight suits have them and everyone wants to be a US Navy fighter pilot now because of the movie.
