Montane Gecko VP 20 Plus Review: A Hybrid Running Pack for Commutes and Trail Days
A 20-litre ultra-vest style running pack with real storage in the back, tested on long runs and commuter runs. Here is what works and what does not.
Introduction
The Montane Gecko VP 20 Plus sits in a useful middle ground. It is essentially a hybrid: a 20-litre ultra vest on the front, combined with a decent amount of storage in the back. That makes it appealing to runners who want race-vest comfort for the front of the body but also need to carry a proper load for work or a full day out.
This review draws on extended testing across long runs, commuter runs, and general everyday use, including one four-hour outing with roughly eight kilos of kit stuffed into the back compartment. Here is what the pack offers, what impressed, and where it falls short.
Key Features and Specifications
The body-hugging design combines a backpack-style 20-litre capacity with a race vest harness. The zippered main compartment will happily pack a commuter-friendly load, including a 15-inch laptop, a change of clothes, and a towel. Two zippered shoulder strap pockets and stretch mesh side pockets add further storage, while front bottle or soft flask holders boost its race credentials.
Fit adjustment is generous: height-adjustable chest straps, adjustable shoulder straps, and a substantial waist strap just below the chest help hold everything steady, even on steepish descents or at race paces. There are also neat touches like a key clip and a removable whistle, plus Polygiene anti-stick odor control for heavier sweaters.

On the numbers side, the pack weighs in at 335 grams, has that 20-litre capacity, and is soft flask compatible with two flasks included. However, it is not bladder friendly, and while there is some rain protection, it is not waterproof.
Front Storage and Flask Handling
The harness is a genuine highlight. The wide shoulder straps do not wrinkle up and cut in the way some packs can; instead they spread the load evenly without feeling burdensome. They are soft and flexible, closer in feel to the straps on a minimal ultra vest, which gives the pack a comfortable, unobtrusive character even when loaded.
The soft flasks slot in nice and low and hold well in the stretchy pouches, easy to insert and pull out. The one quibble: there is no toggle at the top to hold the flask valves in place. As flasks empty, they can start to sag, and during testing it was sometimes necessary to blow into the flasks to keep them inflated and seated properly.

The zippered side pockets are another smart bit of design. Unlike some ultra vests where these sit too far back and become fiddly to reach when tired, these sit nicely around the front without getting in the way. They are big enough to hold a good two hours’ worth of carbs, so a mix of gels, bars, and flapjacks fits comfortably, with room on the other side for a head torch, gloves, or spare socks. Smaller stretch mesh pouches at the bottom suit softer items like gloves and socks that can be squeezed in tightly, though small loose items will fall out.
Fit, Straps, and On-the-Move Security
Adjustability across the chest is good. The sternum and lower straps can be moved up and down to find the fit that works, and the shoulder harness felt secure during testing with no problematic bounce or wriggle.
The chest straps themselves are a weak point, though. They are quite thin, which did not feel as secure as a thicker strap would, and the hooking system is fiddly. Getting the pack on and off, especially with cold fingers at an aid station when in a hurry, is not the easiest task.
The main thicker strap at the bottom uses an unusual velcro mechanism: you velcro on, fold the strap back, then velcro around underneath to hold it in place, with no traditional hook-and-pull system. It did hold during testing, but there is a longer-term concern that the velcro will wear and that once the lower strap loosens, the whole pack will hold less firmly.
Back Compartment and Load Capacity
The back is where this pack earns its keep. Nice big zipper pulls and robust-feeling zips open onto a wide top compartment with a barrel-shaped deep capacity. The entrance is big enough to accept the shoulders of a 15-inch laptop in a slimline case, and there is plenty of depth for towels, trousers, and other bulkier items.
Additional separation comes from a smaller top pocket and another section running into the back mesh, useful for keeping kit organised. A slimline half-pad back mat can also fit inside. One practical touch that sets it apart from similar race vests is the toggle clip on the top that lets you seal the back compartment shut, so nothing wobbles out or flops loose on steeper descents.

Loaded testing confirmed the design: with two 2-litre bottles of water wrapped in a towel plus jackets and clothes packed around them, the light padding took the edge off the lumpy load, and the breathable back mesh kept the pack from feeling heavy and sweaty. One caveat: running light, the pack flaps around a bit, so it performs best when padded out.
Poles can be stowed and secured in dedicated slots, shoulder adjusters on top help pull the weight forward and reduce bounce depending on load, and the rear offers big open pockets. One of these is big enough for a scrunched-up lightweight trail jacket, and bungee cords plus extra tabs secure other bits and pieces. An internal hook is dead useful for securing vital items like a head torch, headphones, or car keys.
Verdict: Who Should Buy It
The Gecko VP 20 Plus shines as a crossover pack. For city-based runners doing office runs in the week and long trail days on weekends, where you want enough clothes, warm layers, and food to be self-sufficient and to get changed afterwards, it is genuinely very good. It also works for lightweight fastpacking trips, such as a night in a mountain hut with one day’s change of clothes, and it is light enough at 335 grams that you can still move fast in it.

It would be overkill for shorter outings of roughly six to ten hours where you carry less obligatory kit; something lighter would make more sense there. It is also not a super minimal ultra vest, so pure racers should look elsewhere. On durability it feels like it will last, and the many thoughtful features add to the value. Priced at 130 pounds in the UK, it feels fairly priced for a versatile, well-featured running pack.
Conclusion
The Montane Gecko VP 20 Plus is a genuinely versatile running pack that switches smoothly between everyday commuting and long weekend trail use. Its comfortable vest-style harness, generous and well-organised storage, and thoughtful details make it easy to recommend for runners who want one pack to do both jobs. The fiddly chest straps, the velcro-dependent lower strap, and the lack of a flask toggle are worth knowing about, but none of them overshadow what is otherwise an excellent crossover option.
