I have this one https://www.amazon.com/High-Sierra-Darter-Hydration-Pack/dp/B01M8NTANS It is killer! I used it as last roo and I fit alot of shit in it. It does have a "3rd pocket" (I dont think it counts) at the bottom that isn't actually a pocket, It's a net that you can bring out so you can carry a blanket or hoodie/clothing. I honestly believe they will let this one in, seeing as it only really has 2 pockets. It's super comfy and light! They have other colors other than the red, I have a black/blue one.

I think you can find these cheaper than this on eBay, this was just the first link I saw.... It's the " High Sierra Darter 10L"

GOOD LUCK ROOVIANS!! CAN'T WAIT TO SEE YOU ON THE FARM.
