ULA Circuit Ultralight backpack + hipbelt inculded!

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 1kg. Circuit rank among the top of lightweight backpacks for every year. 

If you have your total pack weight down around 13,5 kg, and want to feel the freedom of traveling light, this is the pack for you.
Sewn with nearly indestructible ULA 400 Robic fabric, solid robic 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 ULA Circuit can hold a lot of gear with 68 liters of total capacity.
The ULA Circuit has a large extension collar for stowing extra gear, but rolls up easily, using a roll top closure.
There are two accessory pockets in the interior of the pack, a hydration pocket, and a passport-sized pocket for storing valuables. Both pockets are optional and can be easily removed.

The price is final with hipbelt included. Please write us in the note of your order appropriate size of hipbelt you want to add to the backpack. For appropriate size check our size chart. In case of any questions please do not hesitate to contact us.
It is possible to buy also Silnylon backpack rain cover.

In conclusion, only a few reviews, which all are more than positive for this ultralight backpack:

"The ULA Circuit is a high volume lightweight backpack (68L/41 ounces) that’s optimally sized for weekend backpacking trips, thru-hikes, and winter hiking. When used within its recommended load limits, the Circuit is a very comfortable backpack, with a body hugging fit, that belies its capacity. Made with heavier, more durable fabrics (210 Robic, Cordura), this is a backpack that can take some serious punishment, which makes it a best buy in my opinion, if you’re looking for an ultralight-style where long-lasting durability is more important than uber light weight."
"Overall the Circuit from ULA Equipment has worked so well for me that it’s tough to even consider other options on the market and for a lightweight backpacking style, ULA really has this pack at the top of the class. If you like to pack a little heavier or longer trips with more food are your forte’, the Catalyst might be worth checking out, or if you’re packing a little lighter and / or shorter trips are your focus the OHM 2.0 is worth considering as well. In between them though, the Circuit fills the niche for me perfectly on nearly any trip."

Size chart

Hipbelt Sizing Made Simple

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.

Hipbelt Sizing

XS  66cm-76cm

S  76cm-86cm

M  86cm-96cm

L  96cm-106cm

Choosing A Shoulder Strap Style

  • The J straps are the traditional straps, and work best on most men with average builds. 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.
  • The S straps work best on almost all women and men with square shoulders and good posture.

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


Small   38-46  

do 168cm

Medium  46-54

168cm to 183cm

Large     54-61

178cm to 193cm
