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 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
J-straps are the traditional straight straps. Best for: Lean or straight builds, kids, curved and narrow shoulders.
S-straps contour body curves. Best for: Women, athletic and bigger builds, square and wide shoulders.
TIP: If you have a short torso but a larger upper body, contact us for a slightly longer strap. If you are very large in the upper body you might need XL shoulder straps, again contact us.

The Circuit and the Photon had a child, and its name is ULA Kid’s Spark! The Spark isn’t one of those “faux kids backpacks” that looks great on the shelf but doesn’t cut it in the forest — this is a real pack, built tough for serious young adventurers. The Spark has inherited the best from both parents. Built on a “mini-sized” Circuit frame, it has the same carbon fiber hoop, removable aluminum frame stay, and foam/mesh back panel as the Circuit. Slightly shorter and a little wider than the Photon.
The ULA Kid’s Spark wasn’t built for one summer of use; it’s been designed to grow with your child, for summer after summer of adventures. The Spark is custom-built to the current torso & waist fit of the child; however, the adjustable harness system means the pack will grow until your little hiker’s torso fits into an adult small sized pack. With a removable/replaceable hipbelt, the hipbelt sizing is endless. Larger sized replacement hip belts can be purchased as needed from our Parts Shop. The ULA Kid’s Spark is shipped with the adjustable torso pre-configured to your smallies torso size, so you don’t need to worry about getting that “perfect fit.”
This is one tough pack that will give your mini-hiker years of hiking bliss, even if they’re a bit tough on their gear.

Q: WHAT IS A SUSPENSION HOOP?
A: The suspension hoop used in the Spark is our minimal solution to transferring load between shoulder and hip. If you imagine an upside ‘U’ you get a sense of how the hoop is positioned and how it functions. The upper arch of the ‘U’ ties into the shoulder straps, while each leg of the ‘U’ ties into the hipbelt. These points of contact allow for a range of suspension flexibility while being rigid enough to support loads up to 30 lbs. In addition, because the suspension is located on the periphery of the pack body, and the back-panel is stiffened slightly with dual density foam, the result is a pack that can handle the load but does not dictate your child’s movements — but rather responds to how they move.
Q: WHERE DO I STRAP MY CHILD'S SLEEPING PAD?
A: If your child is using an inflatable pad, we recommended storing it in the interior of the pack to avoid punctures. A foam pad can easily be secured beneath the top compression strap that goes over the top of the pack or beneath the front shock cord compression. Although not necessary for optimum performance, positioning the sleeping pad into the interior of the Spark (against the back-panel) is also a good solution.
Q: CAN A WATER BOTTLE FIT IN THE SIDE POCKETS?
A: Each stretch mesh side pocket can accommodate a 1-Liter ‘Big Slam’ style bottle. In general most kids can reach back and retrieve a bottle, drink, and return the bottle to the pocket without removing the pack.
Q: HOW DOES THE TOP OF THE PACK STAY CLOSED?
A: The top of the pack closes like a dry bag (also known as a rolltop) very similar to what river runners use to create a water resistant seal for their gear bags. The back of the collar is slightly taller than the front. Once you are packed, the collar can be rolled down upon itself to effectively create a barrier to water penetration. Once rolled, each side of the collar can be buckled to the sides of the pack or the two yellow buckles on the top can also be fastened to each other.
As for access, once the collar is rolled and fastened shut, you would need to unbuckle the compression straps and unroll the collar to access the inside of the pack. However, the roll-top only needs to be rolled shut when the weather dictates. If the sky is dry, the collar can simply be folded forward. Vertical compression can still be achieved by buckling the collar to the sides of the pack.
