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.

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 proper.
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 cm is your torso length.

Torso Length

S 38cm-46cm

M 46cm-54cm

L 54cm - 61cm

PACK SIZE	TORSO LENGTH	HIKER'S HEIGHT
Small	38-46	do 168cm
Medium	46-54	168cm to 183cm
Large	54-61	178cm to 193cm

Measuring Your Hipbelt Size

For men, use the waist of your pants, and add 5 cm. For example, the waist of your pants is 88cm, add 5cm to get 93cm, which is M size. If you are on the edge of a size go up, so you would wear a large belt

For most women, measure the smallest part of your waist, then add 12cm and go to the chart. For example, your waist is 65cm, add 12cm and get 77cm, so you would be a small belt. If you are straighter through the hips you can add 7cm instead of 12cm.

If you are on the outer edge of a size, order the larger size. (Ex: If you are 96cm, you will notice 96cm is the last number of the Medium Hipbelt and the first number of the Large Hipbelt. You would want to order a Large.)

Hipbelt Sizing

XS 66cm-76cm

S 76cm-86cm

M 86cm-96cm

L 96cm-106cm

Choosing A Shoulder Strap Style

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.

The J straps are the traditional straps, and work best on most men with average builds. They are best suited for people with flat or square shoulders, as their flat shape provides better surface contact and less rub.

The S straps work best on almost all women and men with square shoulders and good posture. 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.Many men with athletic builds, i.e. strong, square shoulders will find the S straps work better. Swimmers, climbers, weight lifters, triathletes, surfers, XC skiers, etc usually prefer the S straps.

DESCRIPTION

ULA ULTRA Circuit – 25th Anniversary Edition

The ULA Circuit you know and love, now reimagined in a special 25th Anniversary Edition that blends proven performance with heritage design and modern materials.
For 25 years, ULA has been part of countless adventures - across deserts, over alpine passes, and along iconic trails like the PCT, AT, and CDT. Since its debut in 2006, the Circuit has become a true trail favorite, earning multiple "Best Gear" awards and remaining one of the most trusted packs among long-distance hikers worldwide.
To celebrate this milestone, ULA has created a limited Anniversary Edition that returns to its roots while embracing cutting-edge innovation. The pack comes in a classic green color, a tribute to ULA’s long-standing connection with green Robic fabrics — now combined with advanced ULTRA 400X, one of the most durable and lightweight materials available today.
The construction is thoughtfully balanced: high-abrasion areas benefit from ultra-durable fabrics, while the overall design remains impressively lightweight (approx. 1091 g). The pack maintains its renowned load-carrying performance thanks to a 1.2 oz carbon fiber and Delrin suspension hoop, a dense internal foam frame, and a single aluminum stay. This combination ensures excellent support, efficient weight transfer, and stability without restricting movement.
Heritage details include a classic open front pocket with static mesh and an elasticized closure, along with original gray grosgrain shockcord tabs. At the same time, modern features such as UltraGrid side pockets, ULTRA hipbelt pockets with YKK AquaGuard zippers, and an integrated 5/8″ top Y-strap closure enhance functionality and durability.
Designed for hikers carrying up to around 16 kg (35 lbs), the Circuit continues to offer the perfect balance of comfort, organization, and reliability, whether you're heading out for a weekend trip or a long-distance thru-hike.

Hipbelt is included with this pack. Select your hipbelt size from the menu below before adding to cart. Refer to our size chart for guidance.
