Hey there!
I've got the half-day and one-day plus, and I'm thinking of finishing the set and going for the three-day. I really like these packs, but I wish First Tactical would tweak a few things. The first thing I'd change is the top dump pocket; either add some wire to the interior compartment to keep it from collapsing in on itself, or make it a hard shell; and I really wish they had the exterior pockets like the Rush 24. Apart than that, these packs are fantastic.
