36 oz - 1021 g Hiking Backpack
Streamlined and efficient, the Swift X is designed to go where you go.
The Swift X is a modern take on a time-tested design. Over 10 years ago, we designed the Swift. Ten years later, we’ve added some modern upgrades to create the Swift X. Constructed from lightweight, durable fabric, the Swift X joins our premium Zero-G line. This ultralight backpack’s simple, modular design means it easily configures to become your perfect pack for any adventure, be it a quick overnight trip or a calendar year triple crown.
The Swift is now offered in a VX21 and LS21 fabric weight. Both fabrics added only 1 oz of weight to the pack for 210 Denier Material Weight. When compared to the 70 Denier Material Weight of the VX07 and LS07, this added durability for the 1 oz weight penalty seemed like a no-brainer to us. For those counting grams, the VX07 and LS07 are still extremely durable, but those looking for an even burlier ultralight pack should consider the VX21.Size Guide
The Swift X is designed to be lightweight, durable, and comfortable. Because we want the pack to be comfortable, the pack weight will vary depending on the configuration. Configured as a Frame-less pack with Pack Bag and Shoulder Straps, The Swift X comes in at 26 oz. / 737 g.
In the Standard Configuration with added Stay and Hip Belt, The Swift X weighs 36 oz. / 1021 g.
With the Vest Harness, you get additional stability in your load carrying and it brings the weight up to 37 oz. / 1049 g.
The Swift X provides ultimate functionality in a simple design. This ultralight backpack has a single roll-top main compartment that holds 38L with an additional 6L extension collar. A Y-strap secures the load top and provides a convenient and easy attachment point for a bear barrel.
Intentionally designed, the Swift X gives you easy access to snacks, your phone, maps, and all those little things you need to keep close at hand. You’ll find you won’t even have the need to take the pack off until you hit camp at the end of the day.
The side water bottle pockets are made from 4-way stretch woven mesh. They are designed so that you can grab items easily while on the go.
Inside the main compartment, there is a zippered pocket for your wallet to keep it safe and secure and easy to access at the first sign of a burger joint.
The Swift X comes in a variety of configurations, so you can get the perfect fit for you and your needs. You can choose from a standard shoulder yoke or flight vest yoke. Each come in 2 sizes.
The Swift X also comes with a removable hip belt available in 3 sizes.
Between the adjustable torso length, removable hip belt, harness options, and removable Delrin Hoop Stay, The Swift X can be dialed in to your exact preferences. Each configuration ultimately changes the weight of the pack from 26 oz. at its lightest to 37 oz. at its heaviest.
While the material used in the Swift X is waterproof the, packs themselves are not water tight. We recommend using a 50L Pack Liner.
The Swift X comes with a removable Delrin Hoop Stay Frame. The ends of the hoop rest on the base of the hip belt, transferring the weight to the hip belt. This design feature makes carrying heavy loads more comfortable and reduces pack sag.
Using the Delrin Hoop Stay and hip belt together increases your load carrying capacity by approximately 10lbs*.
*We recommend a base weight of 12lbs or less even when increasing load weight and using the Delrin Hoop Stay and hip belt.
The Swift X is one of the only ultralight, frame-less pack on the market with an adjustable torso length. This allows the Swift X 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.
Using the Hoop Stay and Hip Belt increases your load carrying capacity by approximately 10 lbs / 4.5 k to 30+ lbs. / 14 k. While you can carry additional weight, we still recommend a base weight of 12 lbs. / 5.5 k or less.
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 S-Curve shoulder straps could 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.

Swift X Backpack Review & OverviewBy: Tuba Solo the Hiker
I was unable to keep the backpack because I'm too short to fit the torso range. I was really disappointed because I absolutely loved the features of the pack, especially the hip belt design. I haven't seen any other makers using this same design. For curvy women, the ability to adjust the top and bottom of the belt is a game changer; my posture while walking (on loaded down test walks indoors) was much better. I was always having to correct my "swayback" that I'd get into unconsciously with most other packs. I actually ordered a stand alone belt that I'm hoping to retrofit to the new pack I ordered from a different brand. There is a good luggage and boot repair place nearby that I hope can help me. The vest design is genius, but not if you're *****. It's weird to be leaving a five star review for something I had to return... hopefully Six Moon Designs will make a shorter version some day - maybe one that would work for kids and short adults.
Almost the pack I’d design if I built packs
This is very nearly the backpack I would build if I had the ability to do so. The attention to detail is excellent and the build quality is fantastic. Coming from other ultralight backpacks on the market, I found this pack solved a whole litany of problems that I’ve been experiencing. Waist belt pockets can be zipped and unzipped with one hand easily. The pack sits snugly against your body and moves with you, rather than bouncing around when the trail gets rough. The flight vest spreads the weight of the pack over a larger area, very effectively reducing fatigue in the shoulders and back. It also provides room for nearly everything you need while on the trail. If I were to suggest some improvements, it would be the flight vest have just slightly deeper water bottle and mesh pockets and slightly larger zipper pockets. I found my standard sized iPhone only just barely fit inside the zipper pockets. The mesh pockets are not super secure and small enough that a snickers bar seemed in danger of being bumped out inadvertently. Some features you don’t realize are useful until you experience them, such as the buckle on the Y strap being able to slide on the strap, making adjustments a breeze. This will be my go-to pack for the foreseeable future. Nice job, Six Moon Designs!
Couldn’t be happier with our new SMD Swift X Ultralight Backpacks!!!
Excellent design, construction and materials all contribute to the best backpacking experience imaginable. This rig acts as an extension of our anatomies, following all of our steps, turns and hops closely without slinging or shifting around and pulling us off balance. The new vest harness and waist belt work together for the most adjustable and comfortable fit possible, making even heavier loads much more manageable! My wife and I have owned a number of different backpacks over the years and find the new SMD Swift X to be a quantum leap forward in utility, simplicity of design, construction and materials. Our heartfelt thanks to the whole SMD team! S&G
Just got back from a break in hike with my swift. Vest seemed to work well. I have a nerve problem in my shoulder and at least on this 7 mile hike no problem. Had the pack on over 3 hours without a break which I usually can not do. Pockets on the vest are small and it will take me awhile to sort them out.
The backpack is badass. It’s like you read my mind. It's the backpack I would make if I was in the backpack making business. All it’s missing is the stench, and I can supply that :) Thanks Six Moons! Stay small, stay local. Don’t become Columbia, or let the Columbias of the business beat you like they did White Stag. Hiker Trash forever!
