Monstrously big, monstrously good.
I’ve had one of these bags for about 20 years. I’ve beaten and abused it, it’s flown all over the world, carried dive gear, been thrown about boats and on and off helicopters. It’s still going strong. It holds a massive amount of gear, carries comfortably, and packs down small when you’re not using it. It’s my favourite piece of travel luggage.
