Which one will hold the most stuff, the Stam or the regular Spy?
I would say the Spy does. The Stam is spacious too, but it's a heavy bag, so you wouldn't want to carry too much anyway.
I have a spy and it is so roomy, and was surprised that it wasn't heavy at all..
I agree, AI think it's the Spy too but they both are really roomy but the Stam is a heavy bag to begin with.
