This is large and very well made. I got it along with the cube, and ended up sending them both home with my visiting son to use on his long (1200 miles) drive back home, before I had a chance to use it. I love it so much I bought a second set to keep. I haven't used it yet but the photos show how roomy the main bag is. Those are 16 oz VSSL tumblers and approximately 10" x 6" ice packs from RTIC plus a couple Awada lunch boxes. Still tons of room. These are beautifully made bags with some very nice details. I have a lot of DOD gear and love everything they make.
