From those grueling east coast ascents to long water carries across the desert, the Arc Air is a durable pack designed to be the ultimate combination of simplicity and function.

Featuring custom Curved Carbon Fiber Air Stays, the Arc Air creates a gap between your back and the pack without the need for a mesh back panel.  The frame transfers weight to your hips, keeping the weight off of your shoulders and providing a comfortable fit.

The ROBIC® fabric is highly durable and provides added abrasion resistance.

Featuring adjustable shoulder straps, an interchangeable belt, and a variety of optional modular add-ons, the Arc Air is sure to become your pack of choice.

  • Constructed from a mix of 3.7 oz/sqyd 100D and 5.8 oz/sqyd 210D ROBIC® Material.

  • Curved Carbon Fiber Air Stays create a gap between your back and the pack without the need for a mesh back panel. The air gap helps keep your back cool while also preventing items from rubbing against you while hiking.

  • The roll top closure keeps water out, and lets you roll down the top as your gear load shrinks. The buckles can be clipped to each other for simplicity, or they can be clipped to the side compression straps to squish down your gear load further. The side compression straps allow you to stand tall items like trekking poles or an umbrella in the side pockets, or they can be detached if not needed.

  • The pack material is waterproof and is constructed using hydrophobic thread, making the pack highly water resistant. We still suggest using dry bags for your important items like your sleeping bag.

  • Large stretchy Lycra mesh center pocket is great for quick access items. Mesh also lets you dry wet clothing and gives you a clear view of your gear.

  • Comfy 3/8" thick by 2.5" wide padded contoured shoulder straps and padded belt. Both the straps and the belt have a daisy chain for clipping on items, and an adjustable position sternum strap is also included. The belt and shoulder straps have 3D mesh on the underside. This gives them a little bit more cushion, and the belt also has more texture for better grip.

  • Side pockets are sized to fit 1 or 1.5 liter bottles. They are positioned low on the pack and slanted forward for easy access without removing the pack. The pockets have drainage holes at the bottom, and elastic that keeps them tight at the top.

  • A top strap, and base straps allow you to lash on extra items to the top or base of the pack. The straps come off if you don't need them.

  • The 60L pack size has enough space for 5-6 days of food and ultralight gear. The pack can be compressed down with the roll top closure straps for short trips or use the top strap and base straps to lash extra stuff to the outside for long carries.

  • All standard Bear Canisters, including the Bearikade Expedition and the BearVault 500 will fit in the upper half of this pack standing on end. There is enough extra girth to either wrap a foam pad around the canister (if you use one) or stand a medium stuff sack vertically beside the bear canister.

  • The short and medium size frames will fit into an airplane overhead bin with the top rolled down to the frame. The tall size frame may not fit unless you pop the vertical frame bars out of the pack.

  • The sides and front of the pack feature a variety of loops for attaching optional add-ons like our top side pockets, shock cord lashing, and ice axe loops.

  • Our torso height adjustment mechanism is is covered by US Patent No. 9,848,687

  • All Zpacks gear has a two year limited warranty against defects in materials or workmanship. Please see our return / warranty policy.

  • Made in the USA.
  • Our ultralight Curved Carbon Fiber Air Stays keeps the pack stiff so that most weight is carried on the hips instead of the shoulders. The frame pieces can be easily removed or replaced.

  • The frame is curved to allow air flow and keep your back cushioned from the pack's contents. The arch is about 2.5" (6 cm) deep.

  • The belt is attached directly to the bottom of the pack frame for the best load transfer.

  • The belt is removable and interchangeable. If you lose weight or need to share the pack between people, the belt can be swapped out. Watch the belt removal video.

  • The shoulder straps and load lifter straps are attached directly to the frame. Load lifters straps come standard on this pack.

  • The shoulder straps can move up or down to adjust the torso height to a perfect fit using our patented torso adjustment mechanism. It works like a conveyor belt. This is great for sharing the pack between people, for growing teenagers, or for resale.

  • The belt provides a full wrap around your back. No need for additional lumbar support.

  • The belt is done with "V-Style" webbing so that the top and bottom circumference can be adjusted independently. This helps wrap your hips much more securely and prevents the belt from sliding down.

  • Collectively, these features provide the additional load transfer necessary for loads up to around 35 lbs (16 kg).

3.7 oz/sqyd 100D ROBIC®

ROBIC® nylon has very high tensile strength for its weight. The material features a fully waterproof polyurethane coating. The exterior is treated with a C6 durable water repellent. This material is used for the main body of the Arc Air.

Weight: 3.7 oz/sqyd (125 g/m²)



5.8 oz/sqyd 210D ROBIC®

We use this heavier weight of ROBIC® to add strength and durability in high wear areas. We use this material for the bottom, rear, and pockets of the Arc Air.

Weight: 5.8 oz/sqyd (197 g/m²)



5.0 oz/sqyd Lycra® Mesh

This mesh provides a superb 4-way stretch and is a great choice for exterior backpack pockets. It has a relatively light weight for mesh, while being difficult to tear. It can withstand getting caught on branches and other typical abrasion that backpacks are subjected to.  


Weight:
 5.0 oz/sqyd (169.53 g/m²)




5.3 oz/sqyd 3D Spacer Mesh

This mesh has a three-dimensional structure which allows airflow and adds cushioning. It has a tricot backing so you can't see clear through the holes. We use it on the underside of our backpack's shoulder straps and belts to absorb sweat, add cushion, and add grip. Our 3D mesh weighs less than most other types.


Weight:
 5.3 oz/sqyd (180 g/m²)

Thickness:
 About 3/32" (2.5 mm)


Torso Height:

To measure your torso height, you will need the help of a friend and a string or cloth tape measure.

Most hikers wear their belt near the top of their hips, however, it isn’t uncommon for hikers to position their belt higher or lower.

To ensure you lock in the perfect fit, we suggest putting a belt on over your clothes in the spot where you’d like to belt to ride. Start your measurement at the center of the belt where it meets your spine.

Lower your chin towards your chest.  This will cause the C7 vertebrae to protrude at the base of your neck. The C7 vertebrae will mark the top of your torso height measurement.

Using the string or cloth tape measure, follow the curve of your spine up from the center of your belt to your C7 vertebrae.  This measurement is your torso height.

Belt Size:

The padded portion of the belt is 1" shorter than the listed minimum adjustment. For example a "Medium (30-45 inches)" belt has padding which measures about 29" tip to tip, has a minimum adjustment circumference of 30" and a maximum adjustment of 45"

To measure your belt size, pull a string or cloth tape measure tight around the spot you’d like your belt to ride. Choose a belt with a minimum adjustment of a couple inches smaller than your actual waist measurement. This will leave room for you to tighten down the belt if you lose a little weight on trail.

The belts on our Arc Series packs are also removable and interchangeable. This will give you the ability to switch the belt out if your waist size changes or if you order the incorrect size by mistake.

AMAZING pack, with a couple minor issues…

I just finished a 13 day, 138 mile thru-hike of the Northville-Placid Trail in New York’s Adirondack Mountains, where I used my brand new Arc Air ROBIC backpack. I was awed by how comfortably a 21 oz pack could carry my 29 pound max load, and by how rugged and durable the pack was despite the abuse heaped on it by the demands of the wild and wooly, under-maintained NPT. Your pack truly exceeded my expectations! There were a couple minor annoyances that perhaps are unavoidable in creating such a lightweight pack. First, the pre-bent back stays aren’t held in place securely enough to remain in their proper orientation without occasional intervention. They would often torque and move around in their sleeves so that they bent sideways or even outward into my back. This was easily fixed by removing the pack and punching the contents and bending the pack until the stays returned to their proper orientation, but I needed to do this often enough that it became an annoyance. Second, the pack would often ride in a laterally unbalanced manner, and I would feel my shoulder straps drape unevenly over my shoulders. This seemed to come and go for no apparent reason, and I never figured out what was going on. I suspect it had something to do with the issue above. Neither of these problems seemed to be related to my pack weight. They occurred as often when I left a trail town under full load as when I arrived in the next trail town under light load. I tried both the Arc Blast and Arc Air before buying, and preferred the Arc Air because the Arc Blast’s mesh compression back panel rubbed uncomfortably against my shoulder blades. However, I imagine that this panel does a better job of holding the stays in their intended bent orientation. I’m not sure what design tweaks would solve the issue in the Arc Air, but if it cost an ounce or two to add extra carbon fiber stiffeners, it would be worth it IMHO. When the pack was working, which honestly was the majority of the time, it was unbelievably comfortable. On a separate note, I read plenty of complaints on-line about the Arc Air’s roll top side compression straps. I found this to be a non-issue for me…the side-mounted buckles worked just fine. In short, despite the problems I noted above, overall I am an extremely satisfied customer of the Arc Air backpack. The pack’s minor issues are vastly outweighed by the benefits of the Arc Air’s ultralight weight and incredible comfort under load.

Super comfy ultralight pack

I got this pack to shed about 16 oz of base weight and improve the comfort over my existing pack, the VC Crown 60. I carried about 23 lbs. for four days in some tough terrain. I was extremely happy with the packs ability to carry virtually all the weight on my hips. My biggest discomfort in the past has been shoulder/trap. pain. The arc is genius. You can let your shoulder load lifters go loose and there is no issue with friction on your back. The lumbar pad was a must for me and could be a big thicker for those looking to carry their weight this way.
