  • Flight 30 is leaner than similar packs making it easier to negotiate cross country through brush.

    The unique vest harness allows runners to jog trails with complete freedom. No matter how fast your change of direction, the Flight 30 stays anchored.

    The Vest Harness not only provides stability to your pack. It adds six additional pockets for holding easily accessible items. No more searching for your snack, GPS or camera. Everything is there for instant access.

    The Flight 30 is a light weight pack with just enough features to get the job done. It leaves home all the useless frills that detract you from the task at hand.

    The Flight 30 is designed to ride high above your waist so as not to interfere with the natural movement of your hips.

    Need additional stability? Add the optional Ultralight hip-belt. The wide hip belt helps stabilize the pack and it's large pockets provide additional storage.


    While there are many Frame-less packs on the market these days. There are none with an Adjustable Torso Length. The Flight 30 allows you to adjust the torso length to adjust to both your body and conditions you're encountering. 

    As a Frame-less pack, you'll want to keep your base pack weight around 8 lbs. / 3.5 k and maximum weight below 20 lbs / 11 k. Comfortable weight depends significantly on the type of load carried and your conditioning.


    Vest Harness

    The Flight 30 works with the Six Moon Designs Vest Harness.  Our unique Vest Harness supports 6-point connection between the pack and your body. This connection system offers several distinct advantages.

    1. It eliminates any sway or bounce in the pack as you walk or run. The pack is fully locked to your body.

    2. It spreads the pack load across a much wider area. Instead of having all of the weight sitting on your shoulders or hips, much of it is spread across your core. This reduces or eliminates sores that can develop when too much weight is concentrated in a single area.

    3. The extra pockets in the vest provides additional storage for items you want to quickly access.


    Years ago when Ron Moak founded Six Moon Designs, his first pack incorporated a Vest Harness, he didn't design it so he could run or hike faster. It was designed to allow him to hike comfortably without a lot of pain. A bout of Cancer had made it difficult to hike more than a couple of hours at a time before stopping due to back pain.

    Incorporating the Vest Harness in the pack provides significant additional support for the back and spine. By spreading the weight, he was able to walk more upright and longer distances without pain.

    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, just that it helped Ron get back to really enjoying backpacking again.

    You are awesome guys. It's only when I got the bag today in Israel after it had traveled from the US that I see what a quality product it is. Can't wait to take it on the trails for a Fastpacking experience. You service and responsiveness was fantastic. Thank you.

    Flight 30 ul

    I love this backpack. The outside pockets are super handy. The chest harness and the waist belt are amazing. The fit is great. The non-elastic p-cord securing strings are genius. Wish : * the front pockets on the waist belt and the chest straps could fit a 500ml soft bottle like this one : * there could be another exterior pocket on the back, in between the ones on the sides.

    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!

    Flight 30

    The Six Moon Designs Flight 30 pack is one of the newest and most exciting backpack on the market for SUL hikers, runners, fastpackers, FKT'ers, peak baggers, and those looking for a small volume backpack that can handle 10 pounds or so of gear and have very little, if zero, bouncing while moving fast down the trail. In late 2013 I found the joys of moving faster down the trail. This lead me into the world of fastpacking and that sort of changed my life when it comes to being out on the trail. As I shared with Six Moon Designs when they published a customer profile on me, The Flight 30 is one of the first packs on the market to cater to this void. It has proven to allow me to move fast, even running, with enough gear and food and water for three or four days on the trail. This really is the niche market that the Flight 30 exists within. There are very few packs on the market that hug the body when moving with three or four days of food, have little to no bounce, and that is amazingly comfortable. The Flight 30 is at the top of the list! View my full review of this pack at Thanks,John Abela

    So close to perfect.

    I'm 6 ft 1 in, 230 lb. I live in the Northeast. My base weight is round 12 lb because I like to bring bear spray, two pillows, and a sleeping bag liner. I used this pack for a few day hikes and some short overnights in the summer. I love how light it is, and how it hugs my back. There's no movement whatsoever. I love the fact it has no frame because I sweat a lot and I think I will easily be able to wash this. I'm not a fan of roll tops, I prefer a lid with a pocket for organization, but that is a small sacrifice. I have used this pack with a vest as well as the new flight shoulder straps. I have used a hip belt also, but I have not found that to be necessary. The few qualms I have are due to my own physical limitations I believe. I have a shoulder injury which prevents me from reaching the large pockets for water or other items. This is where the vest comes in handy, or the hip belt pockets. Although I go as light as possible, I would also really like the ability to attach a closed foam pad to the bottom of the pack. That would help stabilize it when loading / unloading. Right now I use the bungee cord on the back, but it sticks out so much. One thing just occurred to me - would it be possible to have like a waterproof sheet between a person and the backpack? That way you could wash the sheet and the backpack would be protected. There's not a lot of ventilation on this pack so the fact this idea would make my back sweat doesn't matter much.
