Backside Line
There are few packs with a fame just like the ULA Circuit. It’s some of the fashionable thru-hiking packs yr after yr, and we are able to see why after testing it. We had been astonished at how properly it carried heavy masses regardless of being the lightest pack in our lineup. Moreover, the considerate array of options checked almost each field we’d need for a months-long via hike. To prime it off, sturdiness was unimaginable. The powerful materials and glorious high quality stitching gave us confidence this is able to final a full via hike after which some.
A part of what makes the Circuit so successful is that it doubles down on what backpackers really want. The big most important 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’ll be able to match a BV500 horizontally contained in the pack. We appreciated the massive water bottle pockets, even when they had been a bit difficult to succeed in whereas carrying the pack.
However total we’re impressed. It’s one among our prime picks on our full backpacking backpacks information. There’s a motive so many individuals select this pack. For our subsequent journey, we would simply rely ourselves amongst them.

Consolation
We will see why this pack is so fashionable 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. Fortuitously, 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 stated, the massive pack panel doesn’t do a lot in the way in which of air flow. We carried out this spherical of testing in winter, so we couldn’t consider its air flow and temperature regulation in three-season situations. Nevertheless, the froth mesh materials gives 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 significantly by particular person, however we’d have appreciated to see barely wider or thicker straps to distribute the load higher. Nevertheless, as a result of glorious weight switch to the hip belt, we don’t suppose this shall be a difficulty for most individuals.

Options
The Circuit is a extra stripped down pack in comparison with most others on this listing – it’s essentially the most ultralight fashion we examined. That being stated, it nonetheless gives a whole lot of performance for the load. Most significantly, it nonetheless gives the options that thru-hikers are probably to need.
With an infinite most important compartment secured with a roll prime design, the Circuit follows its ultralight roots with a scarcity of inner group. The rolltop mechanism is properly achieved, attaching to 2 aspect straps for extra compression. There are additionally two webbed compression straps – one on all sides – that really feel actually burly. The whole form of the pack tapers right down to a extra compact backside, so the ample compression choices on the highest of the pack is sensible.
The tapering form means becoming a bear can is straightforward. Even a BV500 suits horizontally inside, making this pack an excellent selection for bear nation. It’s value noting that ULA solely charges the BV425 as becoming horizontally,, so check this with your personal bear can of selection and to see what choice feels safe to you.
On all sides we discover generously sized water bottle pockets with adjustable shock twine operating via 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 gives a big house to retailer tons of substances. We wish to stuff our insulating jacket inside after warming up throughout the morning. Moreover, ULA stretched shock twine over the pocket in a cross sample to retailer bigger objects like a moist rainfly. The hip belt pockets are adequately sized as properly. Now we have no complaints there.
ULA gives a couple of customization choices that assist make the Circuit much more versatile. The one prime strap might be switched to a Y strap, which makes carrying a bear can or different massive merchandise externally far 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 good function for accommodating extra physique shapes.
Total, we expect the Circuit gives a large number of options that ought to make via hikers significantly glad. It is going to additionally delight backpackers of any expertise stage.

Sturdiness
Constituted of a powerful 400D Robic Nylon, the Circuit is among the most sturdy light-weight packs on the market. The newest model additionally upgrades to a more durable 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 some of the fashionable packs for via 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 parts are prime quality.

Ease of Use
The Circuit is refreshingly straightforward to make use of, owing to a simple design with out a lot in the way in which of complexity. Like many light-weight packs, the Circuit incorporates a single massive compartment with a roll prime design. The buckles are all properly sized, and compression straps function easily.
One criticism 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 an excellent quantity of stuff, making it straightforward to seize snacks all through the day or retailer a headlamp for night time climbing.
The again pocket system can also be an enormous plus right here. With a layer of stretch mesh and a cross cross of shock twine above it, the again can maintain plenty of massive or small objects. We significantly like stashing our rain jacket on this pocket for surprising storms. Nevertheless, it’s additionally nice for storing an insulating jacket after warming up within the morning. Each storage programs are massive, and we cherished their versatility.
Water bottle entry is a slight destructive right here. Like a whole lot of packs that journey a bit increased, the pockets on the Circuit are additionally increased. This makes accessing and storing bottles a bit troublesome. We had been in a position to contort our arms sufficient to succeed in the bottles, however it wasn’t as simple as we’ve seen on different packs.
