Six Moon Designs ADC Review
"Massive. Featherlight."
The biggest lightweight carry-on backpack I’ve found. The Ultra fabric is best-in-class, the harness is incredibly comfortable, and the main compartment is MASSIVE.

What I like
- 45L at about 2.5 lb, the most capacity for the weight of any travel backpack I know
- The harness is unreal, I carried it on a long hike through South African wilderness and the comfort held up
- Fat hip belt with a big buckle that cinches down solid, and the internal frame cable puts the weight right on your hips
- No frills inside, so the main compartment is a massive box with room to spare
- Ultra material is tough and waterproof, all zips water sealed including the laptop spot. I walked a full day in a downpour and my stuff was fine
- I'm more comfortable setting this down in mud than a ballistic nylon bag. I think it'll outlast you
- Big front stretch mesh, massive water bottle pockets on both sides, hip belt pockets, load lifters, luggage pass-through
- Front quick access pocket is perfect for tech, and the admin panel runs all the way down
- Swappable strap system with different sizes for different bodies
- Surprisingly one of the best values when you factor in capacity and weight
Watch for
- Organization is simple, you've got to be comfortable living out of a big box
- The admin panel goes so deep you'll want a pouch in there to keep small stuff from sinking
- It's soft sided and floppy, and the laptop can catch on the frame going in. I'd use a light laptop sleeve
- 45L is max carry-on for domestic flights but can be trouble in Europe or Southeast Asia. I recommend the 35L for most people
- The Ultra version is expensive, the Robic nylon version costs less but doesn't have that same shell feel
Specs
- 45L (shown) and 35L
- About 2.5 lb for the 45L
- Fabric options: Ultra, Robic nylon, and others
- ADC stands for All Day Carry
