Size Guide



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

  • Sits high above the waist so as not to interfere with the natural movement of your hips.
  • 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 so you can easily dial in your perfect fit.
  • 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 Flight Ultra is a 30L daypack – or multi-day pack if you’re into going super ultralight. Unlike the Flight UL, the Flight Ultra has a new large capacity bottom pocket made of woven nylon, making it even easier to stash and access items on the go efficient, small volume pack.

    There are also 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. With so much convenient storage, you won’t have to shed your pack until you’re ready to make camp.

    The Flight Ultra comes in two fabric options - Robic™ nylon or our new X-Pac VX21 fabric. X-Pac VX21 is a robust fabric by Dimension Polyant. It is made using 3 layers of 210 denier fabric making it not only waterproof but very abrasion-resistant. While VX21 is waterproof the packs themselves are not water tight. We recommend using a 50L Pack Liner.



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

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


    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:

    1. It fully locks the pack to your body, eliminating sway or bouncing when you walk or run.
    2. 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.
    3. 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:

    1. 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.
    2. 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.
    3. The standard shoulder straps are easier to slip out of if you want to take an extended break without the weight of your pack.

    A most excellent product!

    Even though I haven't had the opportunity to put this excellent pack to use yet, I found it much bigger than what I had anticipated, and can't wait to give it a go in action. Everything fits just right after a phone consult with staff, who were knowledgeable and friendly.

    Flight 30 Ultra Running Pack

    My wife purchased this pack for me. I previously talked with Graham with concerns over my height and how the pack would fit. The detailed answers to my questions made me decide to order it. I’ll start off by saying his customer service was excellent. He was of a similar build and height 6”1".

    I personally do not like flashy bright packs and the olive drab color is perfect. Also, I like the markings and symbols as they are not standout white but a nice subdued lighter shade of the pack. Very pleasing.

    I haven’t carried a lot of weight in it yet but about 10 pounds carries really well. My traps and shoulder can bother me at 8-10 pounds but with the vest harness I feel very little in may shoulders. The design makes me feel a comfortable even pressure over the entire pack. Waist, back and torso all feel even weight - extremely comfortable. Easy to reach the water bottle pockets. It feels good speed hiking while using hiking poles. I plan on using it for x - ski.

    There is nothing I dislike about this pack. Appearance and design top notch.

    Perfect Bag for those teetering on Ultra-Light

    My first trial run with this bag was a *great success*. I did a 40 mile loop in PA with my novice backpacker girlfriend, and the bag handled really well the whole time.

    I came from a Sierra Designs Flex Capacitor, which is a 40-60 liter bag, but I noticed I had a fair amount of extra space with that bag, so I decided to upgrade to this. The internal capacity seems correct at 30L but you can add a few by extending the collar. I'm happy that this ability exists, because as the weekend went on I seemed to be carrying more and more of her gear - funny how that happens :)

    The webbing system on the back of the bag is incredibly easy to use and firmly held everything I have strapped to it, including tents or shoes. The side pockets are stretchy enough to hold my cooking system (solo stove). The bag is frameless so the way you pack it will change how it rides - so not using stuff sacks for things like clothes and sleeping bags will help make the bag less bumpy since it'll fill the space.

    Ok, let me get into the adjustability of this bag - this thing has got more straps and buckles than an industrial shipping yard, and it's worth it. You can change the placement of the load lifters, the hip belt has two straps per side, and the chest strap has like 10 inches of adjustable area. It took me about 20-25 miles to get it dialed in right, but then I pretty much forgot about adjustments after that. There are a lot of straps hanging down once you're all strapped in, but they were never knocking against me or anything so it wasn't a problem.

    The hip belt pockets are large enough to hold water filters, phones, small notebooks, or even just cool rocks you find on the ground. The pockets are easily opened with one hand too! There's also a stretchy pocket beneath the bag that you can reach around and easily access while walking. It's great for larger stuff you need periodic access to, like sunscreen or trash.

    If your base-weight is like 7 pounds or whatever, this bag will be too big for you. But if you're lightweight - like around 10-20 lbs, this bag is versatile enough to handle whatever you throw at it - or in it. I don't own a scale so i'm not entirely sure what weight I was at, but judging by my ability to reverse-curl the bag, it was about a 25lbs wet weight. It stuck to my body like glue (once sized correctly and strapped in) and I was unencumbered with it even when jogging downhill.

    All in all, it's a fantastic bag at an unbeatable price.

    Pack feels great! I like the vest style straps with outside pockets to access headlamp or granola bars. Each back side pouch Has great capacity can easily hold a 2 liter soda bottle. I could do 5 days with this pack easily.

    Great fastpacking pack with one minor (fixable) flaw

    I'm just getting into fastpacking and ordered the Flight 30 UL along with similar offerings from Salomon, Montane, and Ultimate Direction.

    I ended up going with the Six Moon Designs because it felt like it offered just a little more capacity (though other bags were advertised as more liters) and with the vest and hip belt, it was definitely the most stable and bounced the least when fully loaded.

    I just took the pack out on a 4 day trip around the collegiate peaks wilderness and it performed excellently. The main compartment easily fit all the essentials along with a few days worth of food. The stretchy side pockets felt like a Mary Poppins bag, I could continually stuff things in them and it seemed like they could always fit more. And then I used the elastic shock cord and top buckle strap to secure things I took on and off through out the day like my rain jacket. The hip belt pockets were a great size to keep a full day's worth of snacks and an iPhone 10.

    I got this pack with the running vest straps and they were awesome, I kept my gps, bandana, lip balm, and other small ditties in there. But, the one issue I had was that the pockets meant to hold bottles weren't deep enough for the 500ml Salomon soft flasks I have. They stuck out about half way. I was able to remedy this though because the bottle pockets are actually sewn on top of the vest's zipper pockets. What I ended up doing was cutting away the fabric of the zipper pocket so the bottle got inserted into the bottle pocket but then ended up going deeper into the zipper pocket. After that, the bottle actually fit perfectly and you can still store stuff along side the bottle in the zip pocket. I think SMD should consider a slight redesign to make those pockets fit a 500 or 600 ml flask by default.

    Other than that, I love this pack and am planning to put a lot of miles on it. Thanks SMD!
