Does anyone own one of these packs?

Which one do you own and why did you choose that one?

Favorite color?

I’m looking for a travel pack simply to put anything civilian related in. Want either of these but is it worth stepping up to the 2100 pack for the addition space? Does it really have that much more room? I’ll never probably use the kidney belt if that means anything.

Please give me your recommendations on which one you have and if you think one is better than the other
