I use a Mystery Ranch Rip Ruck 32 for my EDC/Work backpack. I love it except for the water bottle holders. They are so loose that my water bottles were constantly falling out, getting beat up. So I had to find a solution. What I found works the best for me is Niteize S biners to hook to the loops and to my bottles to hold them in. I've had to change up the sizes as I change my water bottles, but the newest ones I have are #4 for my Hydroflasks. Figured I'd submit this for the carabiner badge as well and see if it will qualify. Does anyone else carry a Rip Ruck?
