5.11 5.11 RUSH24 2.0-GR 5.11 Tactical Backpack Rush 2 (Open Box)

TLDR just buy the size you need and then start expanding the 24(37L) is more than a day pack but I've repurposed mine a few times. Plus they attach to each other. So I started with the Rush 12 for a new work bag. I work 12 hour shifts with a lot of classroom training too so I needed something I can carry over a mile into the office from the parking lot that can carry 3 full meals and some extras such as documents/laptop, the Rush 12 is perfect for me as a daily work bag. I went on a work trip and needed a few days of clothes but not an entire duffel bag(as I learned after the fact), while also taking my day to day things. When I found out that the Rush bags are modular I ordered the Rush 24 while on travel. I'm able to put 3 days worth of things in the 24 and attach my 12 to the 24 making the trip a lot easier because I can carry both bags on my back. This worked out well for hiking and vacation travel. I can use the 24 or 72 for myself and family things, and a MOAB 8/10 as a day bag while my significant other uses the 12 for her packing and the MOAB 6 for day to day things. Get the 4 pack of additional Rush straps, I attached the female part to the bottom of each backpack(not the 72) and the male straps to the MOAB's front. This way each backpack has 4 male and female attachment points (buckle on the bigger bag and fork on the smaller) I since modified my use several times over after expanding to the MOAB series and now have a "fleet" of bags that are all modular. Each backpack has a water bottle holder on one side with a hook and loop IFAK kit on the other side (links below). Each IFAK bag is a bit different, first aid kit for camping/hikes, a diaper change kit, and a toiletry kit. I can attach any IFAK to the side of any bag depending on what we are doing. Day to day uses for me The Rush 72 is massive and perfect for longer trips with the family or if I'm out with the boys. The Rush 24 is now my "DAD BAG" with funny morale patches and a diaper kit on the side. The Rush 12 is a daily work bag MOAB's are used for hikes and other day to day needs. Attachments that I have found to be functional. Rhino Rescue IFAK (home or the tactical pre loaded ones are great, even if you don't know how to use medical equipment in case of an emergency someone else may have the knowledge without the equipment) HLXFF3 Tactical first aid pouch (empty IFAK pouch I use it as a diaper change kit, holds all the things needed for multiple diaper changes and can be ripped off the side for quick access) Generic molle water bottle pouch (I have a fyelo and a Wicktick and they are practically identical)
