3F UL Gear QiDian Pro Review: An 880g Frameless Ultralight Backpack
A 46 litre frameless pack at a claimed 880 grams. Light, affordable and comfortable with a summer load, but the fit and load limits deserve a close look.
Introduction
The 3F UL Gear QiDian Pro is a frameless backpack with a 46 litre main compartment and a further 10 litres of expandable capacity through its roll-top closure, and it weighs a claimed 880 grams. That places it firmly in ultralight summer backpacking territory, where saving grams matters more than carrying heavy loads in comfort.
Frameless packs are far less common on British hills than framed rucksacks, so the interesting question is how much comfort a pack without a frame can actually deliver once it is loaded and on your back. The answer, after a full day of walking with a light summer kit, is that it can be genuinely comfortable as long as the total load stays modest and the fit suits your build.
The pack went out with roughly five kilograms of gear and around eight kilograms all in once food, water and clothing were added. That is ultralight backpacking weight rather than expedition weight, and it shapes everything below.

What follows covers who the QiDian Pro suits, where it performs well, and the fit and load limits worth understanding before you buy.
Who This Backpack Is For
This is a pack for warm-weather, low-weight trips. A summer setup built around a single-skin tent, a two-season sleeping bag and a carefully chosen kit list is exactly the use case it was designed for.
It is not aimed at backpackers who expect to carry 15 kilograms, nor at anyone planning serious mileage all year round with a fully loaded pack. For those trips, a framed rucksack remains the more sensible choice.
Fit matters just as much here. The pack offers plenty of adjustment, but it is cut for taller and broader frames. Anyone smaller or lighter than the benchmark used here should probably look elsewhere, and that is worth stating plainly rather than glossing over.
Main Strengths
Weight is the headline. At a claimed 880 grams, the QiDian Pro is roughly half the weight of a comparable framed pack, and it also costs roughly half as much. On steep inclines that difference is immediately noticeable, because a lighter pack asks less of your legs on every step.

The carrying feel at low weight is better than the frameless design might suggest. With around eight kilograms all in, the pack sits comfortably and does not fight you on climbs. It is a light, uncomplicated carry rather than a technical load hauler, and it behaves well within that brief.
Lightweight, Waterproof Build
The body uses 210D fabric and is described as waterproof, and the roll-top closure works much like a large dry bag. That is also where the extra 10 litres of capacity comes from, since you can keep rolling and packing until the bag is full.
Storage is practical rather than fussy. There are two large water bottle holders on the front, webbing attachment points spread across the pack for customising how you carry extra items, a zipped mesh pocket inside, and a clip for a hydration reservoir. The pack is available in blue, orange, grey and khaki.
Straps, Pockets and Carry Comfort
The shoulder straps are thick, well padded and ventilated, which helps limit sweat build-up where the straps meet your body. The hip belt pockets are unusually large and will swallow far more than a phone and a snack. The hip belt itself is generously long, which is worth noting if you have a narrower waist.
The back panel is where the frameless design becomes a system rather than a compromise. It has a sleeve intended for a folding Z-style sleeping pad, which doubles as cushioning against your back. A cheap foam sit pad fits the same sleeve and works just as well, and because the pack accepts a hydration bladder, a filled reservoir sitting inside the pack adds another layer of padding.

Together, those options mean you can tune the back panel to your own kit rather than relying on a built-in frame.
Things to Consider Before Buying
Load Limits and Back Sweat
A frameless pack transfers load differently from a framed one, and the practical ceiling here is low. Around eight kilograms all in felt comfortable. Fifteen kilograms is a different conversation, and for that kind of weight a framed pack is the right answer.
The other trade-off is unavoidable. With a frameless design your back will get sweaty, no matter which pad you put in the sleeve. It is a reasonable price to pay for the weight saving on a summer trip, but it is a real drawback on warm days.
Fit and Sizing Notes
The pack is generous in size. At 5 feet 8 inches and 70 kilograms with a 30 inch waist, it felt a little big, and the long hip belt reinforced that impression. Taller and broader users are likely to find the fit much better, while smaller hikers may find the pack simply too much around the torso.
There is a lot of adjustment available, which helps, but adjustment cannot change the underlying proportions of a pack. Judge the fit against your own measurements rather than assuming a one-size approach will work.
Buying Advice
At around £72, the QiDian Pro is a low-cost way into ultralight summer backpacking, and the weight saving is real rather than marketing. If your kit list is already light and your trips are warm-weather overnights, it makes a lot of sense.

If instead you want one pack for year-round use, heavy food carries and long days, put the money into a framed rucksack and accept the extra grams. For a dedicated summer setup, and particularly if you are on the taller or broader side, this pack is worth considering.
Conclusion
The 3F UL Gear QiDian Pro does what a frameless ultralight pack should. It cuts a large amount of weight and cost, and it stays comfortable as long as the load stays light. Its limits are just as clear. Keep it under about eight kilograms, plan around a sweaty back, and make sure the sizing suits your frame, and it becomes a sensible addition to a summer kit.
