HOW THIS WORKS
Use the options to fully customize the fabrics, colors, and features of your ULA Circuit to match your style and how you adventure. Next, add on any accessories you need – water bottle pockets, hydration pouch, stash pocket, hand loops, etc. Once you check out, we’ll build it exactly how you made it!
Choose from dozens of Robic, Cordura, X-Pac, or EcoPak fabrics, two buckle colors, ten shock cord colors, 2 stretch mesh options, and multiple strapping options. Note that colors may be slightly different than they appear online. As different fabrics have different weights, the weight of your custom pack will vary from the weights given for non-custom packs.
Your customized pack’s hipbelt, spacer mesh, shoulder straps, and webbing will remain solid black. All custom packs come with a standard hydration port.
Custom packs are final sale; no returns.
ROBIC: Our super tough Robic Hipbelt is the standard hipbelt on our packs. We recommend using the Robic Hipbelt with custom packs using Robic and Cordura fabrics.
X-PAC: Our X-Pac hipbelts have water-resistant YKK zippers. We recommend using the X-Pac Hipbelt with custom packs using X-Pac and EcoPak fabrics.
Front mesh is the stretch pocket on the front of the pack.
STANDARD CLOSED MESH [+$0]: This is the standard black front mesh on all ULA packs.
ULTRASTRETCH™ [+$20]: Upgrade the front mesh to super tough, highly abrasion resistant UltraStretch mesh.
Top straps are the compression straps that go over the roll-top of your backpack.
SINGLE STRAP [+$0]: This is the standard top compression strap on all ULA packs, a single strap that goes over the top of the pack and buckles closed at the front where the collar meets the front panel.
Y-STRAP [+$20]: If you carry gear [sleeping pad/tent] strapped to the top of your pack, you may prefer a Y-strap; a double strap in front that closes at a single buckle in the back where the collar meets the back panel.
Bottom straps are the compression straps that go under the bottom of your pack.
NO STRAP [+$0]: ULA packs traditionally do not have bottom straps.
BOTTOM STRAPS [+$20]: If you carry gear [sleeping pad/tent] strapped to the bottom of your pack, you may want bottom straps, which are two straps that run from the bottom of the back panel to the front, buckling closed where the bottom panel meets the front panel of the pack.
ICE AXE LOOPS
Ice Axe Loops are the loops on the front of the pack where you strap an ice axe. An ice axe loop consists of a fixed webbing bottom loop to hold the axe head in place and an adjustable Velcro top loop to hold the handle. NOTE: If you add ice axe loops, you pack will not have trekking pole loops.
NONE [+$0]: ULA packs traditionally do not have ice axe loops.
SINGLE LOOP [+$10]: One ice axe loop located on the right side of the pack. This is a good option if you typically only carry one ice axe.
DUAL LOOPS [+$20]: Two ice axe loops; one on each side of the pack.
TREKKING POLE LOOPS
Trekking Pole Loops are the loops on the front of the pack where you strap your trekking poles. Trekking pole loops are standard on all ULA packs unless you add Ice Axe Loops to your pack.
DUAL [STANDARD]: ULA packs come standard with dual trekking pole loops.
NONE: If you don’t hike with trekking poles, you can choose to have no trekking poles on your pack.
Our ULA Robic 400 is the toughest standard fabric we’ve ever seen and the fabric we use to make the packs in our pack line. Highly tear and abrasion-resistant, ULA 400 Robic is reinforced with a ripstop weave, increasing tear strength and stitch holding capabilities. Low stretch, this is the perfect fabric for making backpacks, day packs, duffles, and pouches; that’s why we use it! This 100% Robic Nylon fabric has a 3 pass Teflon DWR (Durable Water Repellent) and a 3 pass PU (Polyurethane) Coating, making it highly water-resistant.
COLORS: Red Robic, Orange Robic, Green Robic, Teal Robic, Royal Blue Robic, Blue Blaze Robic, Purple Robic, Grey Robic, Black Robic, Diamond Black Robic
500 CORDURA CAMO
Our 500 Cordura Camo fabrics are made of 100% high tenacity 6,6 filament nylon fibers making them super strong and resistant to abrasion. This fabric is water repellent, thanks to a polyurethane coating. The Cordura does not have a ripstop grid making it not quite as tear-resistant as the Robic. It is also a little heavier than the Robic, adding an extra 2 oz to the total pack weight. Cordura fabrics have been tested in some of the harshest environments, including military applications.
COLORS: Cordura Multicam Camo, Cordura Woodland Camo
Our X-Pac Fabrics include Terrain X-Pac™ VX21, Ripstop Soft X-Pac™ VX21 RS, High Visibility VX25, Rugged X-Pac VX42™, and Camouflage X-Pac X50™. Following is a description of each fabric type, and the current colors available in our customizer.
What is X-Pac™ fabric? Like DCF (Dyneema Composite Fabric), X-Pac™ has its roots in the sailcloth industry where most ultralight, ultrastrong, waterproof fabrics are born. Developed and distributed by Dimension-Polyant, X-Pac™ is a composite fabric comprised of multiple layers of fabric laminated into a single sheet of fabric. The layers in X-Pac™ consist of a Nylon, Cordura, or Polyester face fabric, an X-PLY™ mesh, a waterproof film and a taffeta backing with a water-resistant coating. This technology makes X-Pac ultralight, ultrastrong, abrasion and tear resistant, and highly waterproof. In short, it’s perfect for making outdoor gear, and we think you’ll like it!
TERRAIN X-PAC™ VX21
Terrain X-Pac VX21™ Fabric is one of the most popular high-performance technical fabrics in the industry. The combination of low stretch, waterproof construction, and 210 denier face fabric strikes a near-perfect balance between weight and durability, making Terrain X-Pac VX21™ fabric ideal for backpacks, rain gear, cycle bags, stuff sacks, pouches, and many other outdoor gear applications. If you’re looking for a fabric with a softer hand, try the Ripstop Soft X-Pac VX21 RS™. This laminate fabric is comprised of the following layers: C6 DWR 210 Denier Nylon Face, Black Polyester X-Ply™ at 22°, 0.25Mil PET Film, and a 50 Denier Polyester Taffeta Backing.

RIPSTOP SOFT X-PAC™ VX21 RS
Ripstop Soft X-Pac VX21 RS™ Fabric features a softer hand than the standard Terrain X-Pac™ VX21, while the addition of the ripstop weave increases tear strength and stitch holding capabilities. While it is rated slightly less high in abrasion resistance than the VX21, it’s tear strength is higher thanks to the ripstop checker pattern. The Ripstop Soft X-Pac VX21 RS™ is low stretch, waterproof, and the 210 denier ripstop Nylon face make this fabric ideal for backpacks, rain gear, cycle bags, stuff sacks, pouches, and other outdoor gear. This laminate fabric is comprised of the following layers: C6 DWR 210 Denier Ripstop Nylon Face with Polyester & PU Waterproof Coating, Black Polyester X-Ply™ at 22°, and a 50 Denier Polyester Taffeta Backing.

HIGH VISIBILITY VX25
High Visibility VX25 Fabric is made with UV resistant dyed polyester face fabric and was made to enhance the safety of backpacks, gear bags, cycle bags, and any gear you want people to notice. Available in Hot Lime and Hot Orange. Slightly lighter weight than the VX21 RS and the VX21, this 250 Denier, abrasion resistant, waterproof fabric can be used as a visibility accent color, or for a complete piece of gear that screams, “Can you see me now?!” This laminate fabric is comprised of the following layers: C0 DWR 250 Denier Polyester Face, Black Polyester X-Ply™ at 22°, 0.25 Mil PET Film, and a 50 Denier Polyester Backing.
COLORS: Hot Orange, Hot Lime
RUGGED X-PAC VX42™
Rugged X-Pac VX42™ Fabric is what you use if you’re looking to reinforce high abrasion/ high stress areas of your fabric gear, or if your looking to make a super-rugged piece of gear that’s practically bombproof. X-Pac VX42™ is extremely abrasion resistant, waterproof, and tear resistant. This laminate fabric is comprised of the following layers: C6 DWR 420 Denier Nylon Face, Black Polyester X-Ply™ at 22°, 0.25 Mil PET Film, and a 50 Denier Polyester Taffeta Backing.
COLORS: Black, White
CAMOUFLAGE X-PAC X50™
The Camouflage X-Pac X50™ Fabric uses extra tough 500 Denier Cordura face fabric to create a highly abrasion resistant, tear resistant, high tensile and waterproof material that’s super bomber and can handle even the toughest of conditions. From backpacking gear, to hunting gear, to x-cross backcountry biking gear – the Camouflage X-Pac X50™ can handle the worst of it. This laminate fabric is comprised of the following layers: C6 DWR 500 Denier Cordura Nylon Face, Black Polyester X-Ply™ at 22°, and a 0.5 Mil Shiny Polyester Film Backing.
COLORS: Multicam Black, Ranger Green, Tactical Khaki, Multicam Alpine, Black
ECOPAK + ULTRA

COLORS: Black w/ white flecks.
1. TORSO FIT
- Standing upright, tilt your chin to your chest.
- Locate your C7 Vertabra—the large lump at the base of your neck.
- With flexible tape, measure down the length and natural curvature of your spine to your iliac crest/ the top of your hipbone.
- This measurement in inches is your torso length.
TIP: If you're between 2 sizes, order the smaller size. Still not sure? Contact us.
2. TORSO CHART
We've found most people in these height ranges fall into these torso/pack sizes. That being said, it is always best to measure your torso using the guide above.
If you're between sizes and you are getting a FRAMED pack, we recommend you size DOWN!
If you're between sizes and you are getting a FRAMELESS pack, we recommend you size UP!
If you have questions, or your torso size doesn’t seem to make sense for your height, please contact us.
3. HIPBELT FIT
Use the following method to determine your hipbelt inches, then head to Step 4 to see the hipbelt size you need.
Pant Waist Size + 2".
CURVY HIPS: Smallest part of your waist + 5".
STRAIGHT HIPS: Smallest part of your waist + 3".
Smallest Part of waist + 2".
4. HIPBELT SIZE CHART
Find the hipbelt measurement you calculated in Step 3 on the chart. That will be your hipbelt size.
TIP: If you are on the outer edge of a size, order the larger size. [ Ex: If you are 38", you will notice 38" is the last number of the Medium Hipbelt and the first number of the Large Hipbelt. You would want to order a Large.]
5. SHOULDER STRAPS
The downward slope of your shoulder profile usually determines strap preference. You can assess your shoulder slope profile by looking in a mirror or having a friend look at the angle of your shoulder from the base of your neck to your shoulder point.
If there is relatively little or no downward slope, you have what is referred to as flat or squared shoulders.
If there is a noticeable downward slope, you have what is referred to as standard or sloping shoulders.
J-straps are the traditional straight straps. They are best suited for people with flat or square shoulders, as their flat shape provides better surface contact and less rub.
S-straps contour body curves. They are best suited for people with standard or sloping shoulders, as their contoured shape better hugs your shoulder slope.
TIP: If you have a short torso but a larger upper body, you may need a slightly longer strap. If you are very large in the upper body, you might need XL shoulder straps. Contact us, and we would be happy to make these customizations so your pack is comfortable and fits well.
