Backside Line
There are few packs with a status just like the ULA Circuit. It’s one of the vital standard thru-hiking packs 12 months after 12 months, and we are able to see why after testing it. We had been astonished at how properly it carried heavy masses despite being the lightest pack in our lineup. Moreover, the considerate array of options checked practically each field we’d need for a months-long through hike. To high it off, sturdiness was unimaginable. The powerful materials and glorious high quality stitching gave us confidence this might final a full through hike after which some.
A part of what makes the Circuit so successful is that it doubles down on what backpackers really want. The massive principal compartment is tapered, so many of the house is close to the shoulder space. This concentrates weight there for simpler carrying, but additionally means you may match a BV500 horizontally contained in the pack. We appreciated the massive water bottle pockets, even when they had been a bit difficult to achieve whereas carrying the pack.
However total we’re impressed. It’s one in all our high picks on our full backpacking backpacks information. There’s a motive so many individuals select this pack. For our subsequent journey, we’d simply depend ourselves amongst them.

Consolation
We will see why this pack is so standard on lengthy trails. When loaded up with 34 kilos of weight, we discovered that it carried the load surprisingly properly. The middle aluminum keep mixed with the perimeter carbon fiber / Delrin hoop creates a safe system to maintain the load transferred to the hips. Luckily, we additionally discovered the hipbelt to be nice.
With two factors of adjustment on all sides and a thick buckle within the center, the pack match us properly. That being mentioned, the massive pack panel doesn’t do a lot in the best way of air flow. We performed this spherical of testing in winter, so we couldn’t consider its air flow and temperature regulation in three-season circumstances. Nonetheless, the froth mesh materials affords a little bit of moisture wicking that ought to do higher than a strong face cloth.
We examined the J-shaped shoulder straps and located them to be sufficient. Consolation varies tremendously by individual, however we might have favored to see barely wider or thicker straps to distribute the load higher. Nonetheless, because of the glorious weight switch to the hip belt, we don’t suppose this will probably be a difficulty for most individuals.

Options
The Circuit is a extra stripped down pack in comparison with most others on this checklist – it’s probably the most ultralight fashion we examined. That being mentioned, it nonetheless affords plenty of performance for the load. Most significantly, it nonetheless affords the options that thru-hikers are almost definitely to need.
With an infinite principal compartment secured with a roll high design, the Circuit follows its ultralight roots with a scarcity of inner group. The rolltop mechanism is properly completed, attaching to 2 facet straps for extra compression. There are additionally two webbed compression straps – one on all sides – that really feel actually burly. The complete form of the pack tapers all the way down to a extra compact backside, so the ample compression choices on the highest of the pack is smart.
The tapering form means becoming a bear can is straightforward. Even a BV500 suits horizontally inside, making this pack a terrific selection for bear nation. It’s value noting that ULA solely charges the BV425 as becoming horizontally,, so take a look at this with your personal bear can of selection and to see what possibility feels safe to you.
On all sides we discover generously sized water bottle pockets with adjustable shock twine operating by way of the rim. They’re massive sufficient to carry two water bottles simply. Though, they sit excessive sufficient that retrieving water bottles isn’t as snug as we’d like.
The again pocket is great. Its stretch mesh supplies a big house to retailer tons of drugs. We prefer to stuff our insulating jacket inside after warming up in the course of the morning. Moreover, ULA stretched shock twine over the pocket in a cross sample to retailer bigger gadgets like a moist rainfly. The hip belt pockets are adequately sized as properly. We’ve no complaints there.
ULA affords a couple of customization choices that assist make the Circuit much more versatile. The one high strap could be switched to a Y strap, which makes carrying a bear can or different massive merchandise externally way more safe. Two backside straps may also be added to safe a closed cell foam pad or tent. Moreover, the power to get S formed shoulder straps as a substitute of the usual J form is a superb function for accommodating extra physique shapes.
General, we predict the Circuit affords a large number of options that ought to make through hikers significantly joyful. It would additionally delight backpackers of any expertise degree.

Sturdiness
Made out of a robust 400D Robic Nylon, the Circuit is without doubt one of the most sturdy light-weight packs on the market. The latest model additionally upgrades to a harder mesh for the again pocket, which is a frequent place of failure for backpacks. We had been impressed with the stitching and total high quality when inspecting the Circuit. Though it has a easy design, it’s constructed with a reassuring toughness to each element.
As one of the vital standard packs for through hikers, the Circuit has confirmed itself time and time once more, surviving months of use and abuse. There’s nothing concerning the design or materials choice that offers us pause right here. Even the plastic elements are top quality.

Ease of Use
The Circuit is refreshingly simple to make use of, owing to an easy design with out a lot in the best way of complexity. Like many light-weight packs, the Circuit incorporates a single massive compartment with a roll high design. The buckles are all properly sized, and compression straps function easily.
One grievance we did have was the hipbelt zippers, that are a bit stiff. They open simply with one hand however require two to shut in any respect. That is an space the place many different packs excel. Fortunately, the pockets are properly positioned and maintain quantity of stuff, making it simple to seize snacks all through the day or retailer a headlamp for evening mountain climbing.
The again pocket system can be a giant plus right here. With a layer of stretch mesh and a cross cross of shock twine above it, the again can maintain a lot of massive or small objects. We significantly like stashing our rain jacket on this pocket for sudden storms. Nonetheless, it’s additionally nice for storing an insulating jacket after warming up within the morning. Each storage methods are massive, and we liked their versatility.
Water bottle entry is a slight damaging right here. Like plenty of packs that trip a bit larger, the pockets on the Circuit are additionally larger. This makes accessing and storing bottles a bit troublesome. We had been in a position to contort our arms sufficient to achieve the bottles, but it surely wasn’t as simple as we’ve seen on different packs.
