Lets' face it, every mother has a favorite child, and the Circuit is ours. We don't think there is any pack out there that can compare to the load carrying capabilities, comfort and durability of the Circuit, while still weighing less than 39 ounces. If you have your total pack weight down around 30 pounds, and want to feel the freedom of traveling light, this is the pack for you.
Sewn with our nearly indestructible ULA 210 Robic fabric, solid ripstop side pockets and a huge mesh front pocket, this pack will take the abuse of a 2500-mile hike and beg you for more.
The Circuit utilizes a 1.2 oz carbon fiber and Delrin suspension hoop in conjunction with a dense internal foam frame and a single aluminum stay to give excellent back panel support and maximum load control, weight transfer, and pack rigidity without limiting your range of movement. The Circuit can also be ordered with a 12"18"adjustable harness system that works great for kids. In fact, the youngest person ever to hike all 2663 miles of the Pacific Crest trail was carrying a Kids Circuit.
Hipbelt Sizing Made Simple
For men, use the waist of your pants, and add 2 inches, and then go to the belt sizing section on the order page. For example, the waist of your pants is 36, add 2 to get 38. If you are on the edge of a size go up, so you would wear a large belt
For women, measure the smallest part of your waist, then add 5 inches and go to the chart. For example, your waist is 26, add 5=31, you would be a small belt.
Choosing A Shoulder Strap Style
The J straps are the traditional straps, and work best on most men with average builds. If you are very large in the upper body you might need XL shoulder straps, give us a call for that. Many men with athletic builds, i.e. strong, square shoulders will find the S straps work better. Swimmers, climbers, weight lifters, triathletes, XC skiers, etc usually prefer the S straps.
The S straps work best on almost all women and men with square shoulders and good posture. If you are a short torso, but with a larger upper body, give us a call, we may want to give you a slightly longer strap, there's no charge for it, so don't be shy, pick up the phone or send us an email
Measuring Your Torso Length
Torso measurement is the best guide we have for proper pack fit, but it isn't foolproof. Generally we find that if you are between sizes on the torso it's best to go with the smaller size, if you are between sizes on the hipbelt it's best to go with the larger size. If you have any questions please don't hesitate to call or email.

Q: What does Rec'd Base Weight mean?
A: Recommended Base Weight refers to the total weight of all gear carried (including the weight of your ULA backpack). This includes water bottles and food stuff sacks but not water and food as this will vary during each trip. Knowing your base weight will help you determine which suspension system can best handle your on the trail load.
Q: Can a water bottle fit in the side pockets? If so, can I reach it? How do they close?
A: Each side pocket can accommodate two 1-Liter 'Big Slam' style bottles. A Nalgene-style bottle will also fit, but in your quest to lighten up, that should have been replaced a long time ago! In general most people can reach back and retrieve a bottle, drink, and return the bottle to the pocket without removing the pack. The top of the side pockets are angled for easier access, and adjust single-handedly with a cord lock and internal bungee to open and close.
Q: Can I fit a bear canister into the Circuit? Can it fit horizontally?
A: Every bear canister on the market will fit into the Circuit vertically. Unfortunately bear canisters will not fit horizontally. Keep in mind it is best to pack something between the hard sided canister and the bottom of the pack.
Q: Where do I strap my sleeping pad?
A: If you are using an inflatable pad, I 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 your sleeping pad into the interior of the Circuit (against the backpanel) is also a good solution.
Q: What is the suspension hoop? How does it work?
A: The suspension hoop used in the Circuit 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 35 lbs. In addition, because the suspension is located on the periphery of the pack body, and the backpanel is stiffened slightly with dual density foam, the result is a pack that can handle the load but does not dictate your body's movements --- but rather responds to how you move. Personally, when the loads are kept below 35 lbs, I find this pack to be the most comfortable in the ULA line-up.
Q: How does the top of the pack close? Is it easy to access the main body of the packbag?
A: The top of the pack closes like a drybag (also known as a rolltop) very similar to what river runners use to create a water resistant seal for their gear bags. Basically, 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 rolltop 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..
