Condor Colossus Duffel Bag - 3 in 1 Rugged Tactical Gear Bag - Backpack/Duffle/Shoulder - Lightweight Multicompartment with 52L Storage (Military, Outdoors, First Responders)

I use a Condor Colossus duffle bag. It's plenty large enough for all my gear and then some. It's well made, way cheaper than branded paintball bags, and it has stowable shoulder straps for those fields where the hike from the parking lot to staging is a ways off.
