20 oz - 570 g Pack

The Flight 30 UL gives fast packers complete freedom on the trail.

Designed so your ultralight shelter and camp kit stows in the main compartment and your other gear is stashed outside within easy reach, the Flight 30 UL allows you to go lighter and faster easier than ever before

Size Guide


With the Fight 30 UL, we’ve stripped away all the useless frills and given you a pack with the right features to get the job done.

The pack sits high above the waist so as not to interfere with the natural movement of your hips.

The vest harness keeps the pack close and secure. No more bouncing and swaying.

Option to add UL hip belt for even more stability.

Highly adjustable meaning you can find the perfect fit for you.

Lean design means no hang-ups when negotiating cross country through narrow trails and brush.

Stays with you no matter how fast you change direction.

The volume of the main compartment is 30 liters. But the outer stash pockets are what make the Flight 30 UL so functional on the go. There are 3 pockets on each side of the vest, large stretch pockets on both sides on the front of the pack, daisy chain webbing, and a bungee stasher. Everything you need is within easy reach.

It’s the perfect pack for runners, SUL backpackers, fast packers, and anyone looking for an efficient, small volume pack.



The Flight 30 UL is one of the only ultralight, frame-less pack on the market with an adjustable torso length. This allows the Flight 30 UL to provide unbridled comfort.

When configured as frame-less, the highest recommended base weight is 8lbs / 3.5k and maximum weight not exceeding 25lbs / 11k.


Vest Harness

Six Moon Designs’ unique vest harness supports a 6-point connection between the pack and your body. There are several advantages to this system: It fully locks the pack to your body, eliminating sway or bouncing when you walk or run.

Instead of all of the weight of the pack resting on your shoulders and hips, the vest harness transfers some of that weight to your core. This reduces and eliminates sores from developing on the shoulders and hips.

The vest harness comes with extra pockets, providing additional quick-access storage options.

Vest Harness Health Benefits

Because the vest harness spreads the load bearing to the core, most hikers find it reduces back pain.

Founder Ron Moak discovered this first hand. After a bout with cancer, Moak found that he could only handle a couple of hours of hiking before needing to stop due to severe back pain. A vest harness redistributed the weight he was carrying on his shoulders and hips to his core, allowing him to walk more upright. This additional support allowed him to hike longer distances with less pain.

That’s why the first pack he designed incorporated the vest harness.

If you’ve found yourself unable to backpack as easily and as long as you once did, you may want to seriously consider the vest harness. We make no claims that the vest harness is a miracle cure, but it did help Moak get back to really enjoying backpacking again. And we hope it might help you, too.

Standard Shoulder Straps

There are several reasons you might choose a Standard Should Strap Harness: If you’re used to carrying a traditional backpacking pack and aren’t from the running world, you will probably be comfortable with standard shoulder straps.

If you are a full-chested woman or broad-chested man, you might find the vest harness constricting. In this case, the standard shoulder straps will provide a better hiking experience.

The standard shoulder straps are easier to slip out of if you want to take an extended break without the weight of your pack.
