In vanilla they're both the same in size and stack, with the difference being on how they affect stats. Both thieves backpacks (small/med) are an improved version of the common backpacks, that's why the price difference (5k Cats vs 1.5k Cats for medium). I did modify the mod files for my own gameplay, but anyone is free to do their own way. cheers :)

The fact that they have almost no impedance on your combat abilities is the reason why they are not the same, their price is still fairly cheap but that is also my opinion.

Nice mod, also what I was looking for. Just as an opinion I feel that the thieves backpack should have the same stack sizes as the regular ones since they are more expensive.

No problem, not a huge fan of these infinite backpack space mods, personal preferance, enjoy!

I was looking for this, thank you.
