Lets' face it, every mother has a favorite child – ours is the Circuit. Weighing in at just over two pounds, we don't think there's a pack out there that can compare to the load carrying capabilities, comfort, and durability of the Circuit pack. 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. The Circuit has been the most popular pack on the Pacific Crest Trail for the past 3 years according to the Halfway Anywhere annual survey of PCT thru hikers.

The Circuit pack 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 you excellent back panel support, maximum load control, weight transfer, and pack rigidity without limiting your range of movement. The Circuit can be ordered with a 12" to 18" adjustable harness system that works great for kids. In fact, the youngest person ever to backpack all 2,660 miles of the Pacific Crest Trail was carrying a Kids Circuit!

This is one tough pack that will give you years of hiking bliss, even if you are a bit tough on your gear. This pack will take the abuse of a 2,600 mile hike and beg for more.

“Base weight” refers to the total weight of all gear carried — including the weight of your ULA backpack.

Knowing your base weight will help you determine which suspension system will best handle your load on the trail.

Colors Available: Gray, Orange,Blue Blaze

HIPBELT SIZING MADE SIMPLE

 
MEN
For men, use the waist size of your pants and add 2 inches. The “HIPBELT SIZE” option above includes numbered measurements. The number you calculated (waist size + 2) will determine the size you need. If you are on the outer edge of a size, order the next size up! Example: If you wear a size 36 pant, add 2 to get 38. Since 38 is the last number of the Medium Hipbelt and the first number of the Large Hipbelt, you would want to order a Large.
 
WOMEN
For most women, measure the smallest part of your waist and add 5 inches. If you are straighter through the hips, add 3 inches instead of 5. The “HIPBELT SIZE” option above includes numbered measurements. The number you calculated (waist size + 5) will determine the size you need. If you are on the outer edge of a size, order the next size up! Example: If your waist size is 26, add 5 to get 31. You would need a Small hipbelt.
 

MEASURING YOUR TORSO LENGTH

 
Torso measurement is the best guide we have for proper pack fit, but it isn’t foolproof, there are many other factors which will determine a proper fit. If your torso measurement is between 2 sizes, order the smaller size. If you have questions, or your torso size doesn’t seem to make sense for your height, please email peter@ula-equipment.com and he can guide you along. If you are between sizes on the hipbelt it’s best to go with the larger size, it gives you more padding and puts the pockets in a better position.

To accurately measure your torso length for a correct pack fit, grab a buddy and follow the steps below…

  • Standing upright, tilt your chin to your chest.
  • Locate the largest lump on the back of your neck. It should be located close to the base of your neck.
  • From this large bone, measure (with the flexible tape) down the length and natural curvature of your spine to the top of your waist band, the top of which is resting on the top your hipbone. This measurement in inches is your torso length.

 

PACK SIZE TORSO LENGTH HIKER’S HEIGHT
SMALL 15″ – 18″ UNDER 5’6″
MEDIUM 18″ – 21″ 5’6″ TO 6’0″
LARGE 21″ – 24″ 5’10’ TO 6’4″
X-LARGE 24″ + OVER 6’4″
KIDS ADJUSTABLE 12″ – 18″ KIDS

CHOOSING A SHOULDER STRAP STYLE

 
J STRAPS
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, surfers, triathletes, XC skiers, etc usually prefer the S straps.
 
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.

Q: WHAT DOES RECOMMENDED BASE WEIGHT MEAN?

A: “Base weight” refers to the total weight of all gear carried — including the weight of your ULA backpack. This weight also includes things like water bottles and food stuff sacks, but not the weight of water and food as this will vary during each trip. Knowing your base weight will help you determine which suspension system will best handle your load on the trail.

Q: DO I NEED THE S-STRAP OR THE J-STRAP? WHAT’S THE DIFFERENCE?

A: 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,surfers, triathletes, XC skiers, etc usually prefer the S straps.

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 singlehandedly 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 back-panel) 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 back-panel 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, we find this pack to be the most comfortable in the ULA line-up.

Q: HOW DOES THE TOP OF THE PACK STAY CLOSED? IS IT EASY TO ACCESS THE MAIN BODY OF THE PACK BAG?

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.
