ULA Ultra Circuit Pack

NEW FOR 2024: At ULA, we understand every trip is different, and your pack and gear needs can change with each trip, so we've updated the ULA pack line to be more versatile than ever to keep up with how you adventure. What's new? Combination ice axe/trekking pole loops are now a standard feature; the weather is unpredictable, and we believe your pack should be able to adapt as fast as you can. We've also added low-profile loops to the top and bottom of these packs to accommodate removable top Y-strap and/or bottom straps. Purchase an ultra-light strap kit for your pack and be able to instantly add the capacity to strap larger items (tent, food storage, or sleeping pads) to the top or bottom of your pack as your gear needs change. And while we were at it, we made them prettier.

The same Circuit you know and love, only stronger and lighter than ever. Purposefully constructed of Ultra 400X in high abrasion areas (bottom, back panel, and pockets) and Ultra 200X in low abrasion areas (sides, front, and collar), we've selected a fabric matrix that maximizes durability while keeping the pack ultralight [33.8 oz!]

In our commitment to making quality, durable backpacks that last a lifetime, we've been hesitant to build packs out of many popular ultralight fabrics. Why Ultra? 15x stronger than steel by weight, twice as abrasion resistant as standard 420D nylon, and waterproof to 200 psi, we've finally found an ultralight fabric that matches our high standards. Front pocket is ULTRA StretchMesh for added abrasion resistance. Note that to maximize water-resistance of the ULTRA Circuit, these packs do not have bladder hose ports. 

We don't think there's a pack out there that compares to the load carrying capabilities, comfort, and durability of the Ultra Circuit. The Ultra Circuit utilizes a 1.2 oz carbon fiber and Delrin suspension hoop, 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. Front mesh pocket, dual hipbelt pockets, and Ultra 400X adjustable side pockets make it easy to stay organized whether you're on a thru or just out for the weekend. If you have your total pack weight down to around 30 pounds and want to feel the freedom of traveling light, the Circuit is for you.

SHOULDER STRAPS

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.

J STRAPS
J-straps are the traditional straight straps. They are best suited for people with flat or square shoulders, as their flat shape provides better surface contact and less rub.

S STRAPS
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.
