That's about the closest I've seen in the books, A4BG. I just ruled with my group that it was part of their Lifestyle payments. Better lifestyle in clothing, better tacgear they had unless they bought the high-end stuff like the Combat Load Vest in Arsenal.
For the characters I created, I say their Lined Coat (Which is a Longcoat of any sort, like a Trenchcoat or a Duster) has specially made synthleather pockets for the gear. Lots of room for magazines, gear, and so on.
Oh, Survival Kits come with a Backpack or Courier Satchel. They'd have to with all that stuff.
MedKits I always pictured as ranging from First Aid Kits to Courier Satchel-sized items depending on their rating. I usually bought a bunch and left them all over the place, as well as carried one with the character after it's had the bright white with a red cross on it painted over with black paint. Suddenly a MedKit turns into a briefcase with a shoulder strap!
