38.8 oz - 1100g Ultralight 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 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 27 oz. / 765 g.
In the Standard Configuration with added Stay and Hip Belt, and Flight Vest The Swift X weighs 38.8 oz. / 1100 g.
With the Vest Harness, you get additional stability in your load carrying and it brings the weight up to 40.2 oz. / 1151g.
The Swift X provides ultimate functionality in a simple design. This ultralight backpack has a single roll-top main compartment that holds 41L with an additional 10L 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 27 oz. at its lightest to 40 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.

Swift X Backpack Review & OverviewBy: Tuba Solo the Hiker
I had breast cancer in 2017 and was told that because of the danger of lymphedema (a complication of having lymph nodes removed to check for cancer) I probably shouldn't carry an overnight-sized backpack again. Despite this danger, I have made the choice to continue to backpack. However, with shoulder straps it has not been very comfortable because of the amount of scar tissue I have in my underarm area. As a result, I have chosen to use very well padded backpacks, even though they are relatively heavy. When I saw the vest option for the Swift X I thought it might help with my issues, and indeed it has. I had a lumpectomy and am medium-chested (C-D cup size), so I don't know if the vest would work as well for people who had mastectomies or are who have larger breasts, but for me it's been amazing. There is no underarm rubbing at all because the vest doesn't go up to my underarm area. This means that the area where lymph nodes were removed has no additional pressure on it and I suspect this reduces my chances of developing lymphedema, although I don't know that for sure.
Three other things that I really appreciate about this backpack are: the transfer of weight to my core (I actually had sore upper abs after my latest Yosemite trip with a load that pushed the 35 pound limit); the ability to cinch the pack down to day-pack size for summit days; and the waist belt system which is great for my curvy hips. I've always preferred women's fits in backpacks but this uni-sex pack works great for my body.
All around, I couldn't be more pleased. This pack will be the one I use exclusively for all but the shortest day hikes.
Fixed Whitney's van at my shop and he turned me on to Six moons. Bought the swift x. Just did a 3 day 25 mile trek with 35 lbs. I own lots of packs. Best 1 I've ever had !!!!!!
Just got this pack in the coyote brown VX21, with the standard shoulder straps bc the vest wasn’t available to me. The pack is not exactly ULTRAlight but a typically sturdy and versatile lightweight SMD pack. If you know SMD, you know what to expect. One thing that did surprise me, though, is, compared to my SMD Fusion 65 (1st gen) this supposedly 40/45/49 liter pack is an absolute GIANT. I assumed the Swift would sit/fit in between my Fusion 65 and my 30’ish liter SMD DayBreaker (now Wy’East) but it’s definitely bigger than the Fusion. I’d be interested to learn how these sizes are measured (thought I knew but seeing these two next to each other has left me confused). That said, I’m not at all unhappy with the pack, just surprised with the size(ing).
Second thing I’ll say is there’s a lot of excess strapping. But I’ve actually put that to good use (I think) so instead of trimming it I’ve tinkered a bit: (1) I’ve redone the yellow paracord to run across the front pocket as well as sides, and (2) more importantly, and ingeniously if I do say so myself, I’ve run the shoulder straps through the extra attachment points otherwise reserved for the vest harness by running them diagonally across the back (through the hip belt attachment gap). This way the pack should sit closer to my back, like the vest (remains to be tested in the field but maybe try this hack if you, like me, wanted the vest but could only get hold of the standard yoke).
This pack was so comfortable. I bought with the standard type shoulder straps and they were fine. Hip pockets easy to negotiate and held quite a bit. 4 night, 3 day trip on the Three Capes trail at bottom of Tasmania (Australia). Did not have to carry tent nor sleeping mat but I know exactly where they'll fit for next trip.
This is my first dip into the vest harness style and I LOVE it. Haven't been able to get on an overnight quite yet, but some weighted day hikes have been so great! Love the vest harness, the side pockets, all of it. Thanks for making a rad pack!
