What you should look for

(and what we test for)

Weight

When picking an ultralight backpack for outdoor pursuits like hiking or camping, pay attention to the weight - you want something feather-light yet sturdy enough to handle your gear without weighing you down.

Design and Comfort

Look for intuitive design elements like ergonomic shoulder straps, breathable material to avoid sweat buildup, and adjustable components to ensure comfort and fit during long hiking or climbing sessions.

Material and Durability

The material of your ultralight backpack should be both durable and weather-resistant, as it needs to hold its own against various elements such as rain, snow, and rough terrain over a prolonged period.

Capacity and Organization

Finally, consider the backpack's capacity and layout - it should have enough room for all the essentials and boast smart, accessible compartments to keep your stuff organized and easy to retrieve on the go.

A noteworthy aspect of the Gossamer Gear Mariposa 60 is its durability. Buyers attest to the quality of the materials used, despite its lightweight nature. Its rugged ripstop nylon body and DCF bottom make it quite resilient, even in rough terrains and bad weather.

On the flip side, there have been a few concerns. Some users found the side pockets a bit high for easy access when on the move. Others wished for a top zip for the main compartment, instead of roll-top closure, for swift loading and unloading of gear.

While the price could be a slight turn-off for some (it's no cheap investment), numerous buyers have vouched for the backpack's value for money, praising its comfortable design, large volume, robustness, and revolutionizing their backpacking experience.

The backpack's lightweight structure and well-padded straps ensure a high level of comfort, even when the bag is loaded to capacity. Of course, individual comfort can vary, and some smaller users reported the backpack feeling a bit too bulky.

The enormous 60-liter volume leaves no shortage of storage space, although some users commented that the pockets could be more accessible. The seven built-in pockets and main compartment offer plenty of organization potential.

Value

The Mariposa 60 backpack may be towards the higher end of the price range, but its performance, adaptability, and comfort make it a worthwhile investment for avid backpackers or those planning long-duration treks.

Weight

The Gossamer Gear Mariposa 60 is an ultralight backpack, but it doesn't compromise on comfort or storage capacity. Despite its impressive volume, the backpack remains relatively light on the shoulders and easy to carry, particularly for longer treks.

Review Roundup

The ULA Equipment Circuit is an ultralight backpack that’s gaining rave reviews among backpacking adventurers for its impressive blend of lightweight construction, durability, and superior carrying capacity. Built for those multi-day hike or a weeks-long expedition, this backpack does not mess around when it comes to getting the job done.

Despite tipping the scales at a feather-light 41 ounces, the ULA Circuit doesn't sacrifice on durability. Buyers speak fondly of its Robic fabric, a specialized blend that manages to combine lightweight construction with tough-as-nails resilience. It’s renowned for standing up well to wear and tear, making it a reliable choice for those who hit the trails regularly.

Comfort is another stand-out feature highlighted by users. With a well-padded back panel, the contoured shoulder straps and hip belt can comfortably handle loads of up to 35 pounds, providing ample support and reducing the likelihood of chafing – a big plus point for long-distance hikers.

Buyers also appreciate the Circuit's impressive carry capacity. With a volume of 68 liters, it offers ample space for overnight gear with some room to spare. A neat feature users have lauded is the collapsible roll-top closure, which allows for extra storage but can be rolled down to reduce the overall pack volume when needed.

Pockets abound on the ULA Circuit, side and mesh pockets providing easily accessible storage for water bottles, trekking poles, or snacks. Positive feedback was found for the top pocket which can be removed to save weight or used for easy access to trail essentials.

On the flip side, some users have commented they found the hip belt pockets to be a little on the small side, struggling to fit larger smartphones. It appears that while the bag excels in terms of weight and storage, there may be slight drawbacks when it comes to pocket sizing.

Another point of contention was the lack of an included rain cover. While the backpack itself is constructed with water-resistant Robic fabric, some users expressed desire for an additional layer of protection when mother nature decides to open the heavens. This, however, is a minor quibble and readily solved with an inexpensive, separate purchase.

Comfort

Comfort is a standout feature praised by many users. The ULA Circuit comes with a well-ventilated back panel and convenient hip belt pockets. The shoulder straps are thickly padded, reducing pressure points and preventing clashes with heavier loads.

Durability

Constructed with Robic fabric, this pack is known for its serious resilience. The material strikes a superb balance between lightness and durability, and can withstand a fair share of outdoor thrashing.

Load Carrying Capability

In user reviews, the Circuit often gets high marks for its load carrying capacity. It can carry up to 35 pounds comfortably, and handles well even when fully loaded.

Material

This ultralight is made from Robic fabric, which combines low weight with high durability to keep your gear safe and protected. It's also known for its water resistance, which makes the pack an excellent option even in rainy conditions.

Storage Capacity & Accessibility

The Circuit offers a sizable main compartment, along with an array of useful extras – a large mesh pocket on the front, two side pockets for water bottles, and hip belt pockets for easy-to-reach storage. Some users, however, found the water bottle pockets a bit tough to access while walking.

Value

With its robust construction, great storage capacity, and above-average comfort, the ULA Equipment Circuit provides remarkable value. It comes with a higher price tag compared to some other ultralight backpacks, but most users find the investment well worth it for the significant benefits in terms of durability, comfort, and carrying capacity.

Weight

The ULA Equipment Circuit lands right in the sweet spot for ultralight backpacks. It's not the lightest on the market but its balance of weight, function, and durability is top-notch. It manages to offer a hefty carrying capacity while keeping the weight at a manageable level, perfect for those long trails or multi-day hikes.

Review Roundup

The HyperLite Mountain Gear 3400 Southwest is a real gem in the arena of ultralight backpacks. This backpack stands out among the competition for its superior weight-to-volume ratio. It's unbelievably light on the shoulders, yet manages to provide ample space for all your gear in its 55-liter capacity. The seriously lightweight power comes from the use of Dyneema Composite Fabric, known for its exceptional strength and durability.

What really sets the 3400 Southwest apart, and what many previous buyers rave about, is its resilience in all kinds of tricky weather conditions. This backpack could easily be your trusty companion whether you're hiking through a rainstorm or manoeuvring your way through a dry desert. The water-resistant feature really works wonders and the external, hard-wearing material rebuffs any light scratches.

Comfort was a high scoring trait for the 3400 Southwest amongst online reviewers. The well shaped and designed shoulder straps distribute weight evenly, providing much-needed comfort on those long treks. Adaptive fit hip belts and universally comfortable padding work together to make this bag a delight to wear.

One slight hiccup many users mentioned was regarding the limited amount of external pockets. While the backpack does have beneficial side pockets, it lacks outer small pockets for those pieces of gear - water bottle, snack bars, map - that hikers like to keep easily accessible. This is something to consider if quick-access pockets are a must-have for your hiking comfort.

Despite minor drawbacks, the HyperLite 3400 Southwest seems to be a unanimous favourite for serious backpackers. Users praised its versatility, its excellent build quality and of course, how wonderfully light it is. It's safe to say that this backpack is recommended by many real-world adventurers who need a dependable, functional, and lightweight solution for their journeys.

Storage Capacity & Accessibility

3400 cubic inches of storage capacity - that's a whole lot of gear and provisions. It doesn't have many extra pockets, but the overall accessibility is user-friendly and intuitive. The roll-top design allows for easy access to items packed at the bottom of the bag.

Value

The bag is pricey, no escaping that fact. But if you consider the high-quality material, durability and the amount of thought that's gone into the overall design—it appears to be a case of getting what you pay for. It's likely to outlast cheaper alternatives, adding value in the long term.

Weight

The HyperLite Mountain Gear 3400 Southwest is designed with weight-conscious outdoors people in mind. With a stripped down design that doesn’t compromise on durability or quality, it's not the lightest on the market, but it sits comfortably within the range of lightweight backpacking options.

Doubling down on comfort, the bag sports contoured shoulder straps and a hip belt that's easily adjustable, ensuring a snug fit whether you're petite or more on the burly side.

The durability of Gorilla 50 has also drawn many buyer's attention. Its main body made out of a high-tensile nylon fabric strikes an impressive mix of featherweight lightness and bear-like toughness. It seems quite capable of tackling the trifecta of dirt, dust, and downpours with ease.

The occasional gripe aside, the Gorilla 50 seems to stake its claim in the budget niche and does it with confidence and style.

Material

The material of this backpack is where it shines, and a big contributor to its light weight. The Robic nylon fabric is both water and tear-resistant lending durable quality to the pack.
