36oz - 1021g 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 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.
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.

Swift X Backpack Review & OverviewBy: Tuba Solo the Hiker
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!
I upgraded from the Flight 30UL. 20 lbs is MUCH comfier with the swift x. 25-30 lbs is still quite comfortable. I haven’t yet exceeded 30…
I have carried this pack now for three months, thru-hiking. The material has held strong, the fit is great, the adjustability is great. I am VERY GLAD to have NOT purchased a seam-sealed pack, the breathability long term is really important. 2L in each side pocket easy. I added bungee chord to the back. Tenor uke in the back mesh fits perfect. Hip belt pockets hold camera/garmin well. Comfortable/durable/affordable. Thank you Six Moons-
Such a great pack. We used these for up to 10 day stretches making a thru-hike in the wilderness around Yellowstone, and it’s shockingly comfortable with a full bear canister (or even 2!) packed inside. Lots of straps make it easy to dry wet gear or lash things to the outside, and snug it up when it’s less full.
I highly recommend buying packing pods to keep gear organized, because this pack doesn’t contain interior pockets. A dry bag is probably a good idea too if it’ll be rainy and you’re using down, but the pack is very weather resistant. We tried the vest harness and regular shoulder straps; both are great, depending on body type.
The Swift X is also a surprisingly good alpine/climbing pack. I used it working this year’s Valdez Ice Climbing Festival and it was great! Ice tools fit on it well, and it holds a rope securely on top (although you have to loop the top strap around the rope once before clipping it, or it will slide down the pack). When you remove gear to rack up, it’s easy to snug the pack against your back for smooth climbing.
It’s versatility and durability, combined with its light weight, replaced two other packs of mine. I’m looking forward to years more adventuring with it, and highly recommend it!
