Salomon Sense Pro 6: the full RunMorph review

Salomon claims 141 grams for the Sense Pro 6. Le Comparatif du Trail weighed it at 149 grams in size L. Eight grams off on a vest that sells for 180 euros and is meant to replace both the Sense Pro 5 and the Sense Pro 10: that double promise is what this review is really about. It delivers on fit and comfort, much less so on rear storage and hydration.

Salomon Sense Pro 6: the vest meant to replace two generations in one go

Salomon stopped producing the Sense Pro 5 and Sense Pro 10 at the end of 2024 to merge them into a single model, the Sense Pro 6. It is a risky move: a runner who loved the lightness of the 5-litre version and another who relied on the ten litres of the big one now have to find what they need in the same vest. Salomon chose to side with minimalism rather than volume, and positions the Sense Pro 6 between the S/Lab Ultra 12 and the S/Lab Pulsar 3, without making it part of the S/Lab range itself.

RunMorph's advice: if you are torn between the Sense Pro 6 and a model from the ADV Skin range, ask yourself one question. Do you want to run fast and light with two flasks, or do you want to stash everything without thinking about it? The first answer points to the Sense Pro 6, the second to the ADV Skin.

Objective technical data

The gap between the 141 grams claimed by Salomon and the 149 grams measured in size L is modest, eight grams, but it confirms a useful rule for any minimalist vest purchase: the official weight almost always refers to the smallest size available, never to an M or an L.

Who is the Sense Pro 6 for?

The runner who stacks up 20 to 50 km outings

This is the Sense Pro 6's core target. Two flasks, two stretch front pockets for nutrition, a tunnel pocket for the waterproof jacket: enough to cover a two to five hour run without ever stopping to reorganise your kit.

The racer aiming for an ultra with light self-sufficiency

The 6-litre volume and Custom Quiver compatibility let you go longer, as long as you accept buying the quiver separately to carry poles without them bashing against your back.

The runner who wants a bladder or real rear storage

This profile is not catered for. The lack of dedicated hose routing and a zipped back pocket points you instead towards an ADV Skin 5 or a vest with a built-in quiver like the Black Diamond Distance 6.

The field test: the snuggest fit in the segment, but a real weakness at the back

Independent tests agree on one point: the Sense Pro 6 is one of the best-fitting vests in its category. A French field test run over several outings describes a cut that sits high on the back and wraps the sides well, with a Quick Link system that adjusts the chest strap in a second, even with cold hands. A month of independent testing in the United States, including a 32 km loop mixing road and trail and then a half marathon on softer ground, confirms this stability and even reports zero bounce, including when climbing over fallen trees or running on packed sand.

The two sources disagree, however, on weight distribution. The French measurements point to a slight forward imbalance caused by the lack of a zipped back pocket: anything a bit heavy like a headlamp, a smartphone or a set of keys has to move to the front pockets, which adds small bounces on technical descents. The American test, which did not have to carry heavy items like these on its routes (road and runnable trails rather than technical descents), noticed nothing comparable. At RunMorph, the reading is simple: on runnable terrain with a light load, the Sense Pro 6 doesn't move. On a technical descent with a headlamp and night gear in the front pockets, you feel the imbalance.

Breathability, on the other hand, gets unanimous praise. The thin fabrics and perforated foam reinforcements on the back wick moisture well, even during a half marathon run back to back over two consecutive long-run days. Neither source reports hot spots or chafing, including on the shoulders and lower back, an area that is usually sensitive on thin-fabric vests.

Compartments and accessibility: everything up front, almost nothing at the back

The Sense Pro 6's big strength is pocket access on the run. The two open front pockets, stacked under the flask sleeves, are deep enough for gels, bars and even an extra 250 ml flask. The two zipped pockets above them secure your smartphone and bank card, and the small zipped pocket at the top of the left strap takes keys or a collapsible race cup. The lower tunnel pocket, open on both sides and made of stretch fabric, is praised by both tests as one of the vest's best ideas for storing a waterproof jacket without it bouncing.

At the back, the picture flips. The upper pocket is not closed, which makes it reachable on the run but means you cannot confidently store a headlamp or an emergency blanket in it: those items bounce around freely unless the vest is backed up by good organisation up front. This is the central flaw flagged by the French test, and there is no native fix on this model.

For poles, the elastic loops supplied front and back are judged unconvincing by field tests: the poles move and knock against your back or ribs. The Custom Quiver, compatible but sold separately, remains the only truly reliable solution, with a useful side benefit: it shifts weight towards the back and partly makes up for the missing zipped pocket.

Hydration: two flasks yes, bladder no

The Sense Pro 6 is designed for flasks, not for a bladder. The two 500 ml Salomon S/LAB soft flasks supplied sit high in the front pockets, with cinch straps that limit bounce as long as they are properly tightened. It is an effective system for two to five hour outings with regular refuelling.

The problem comes as soon as you want to add a bladder: the manufacturer provides neither dedicated hose routing nor a clearly identified attachment for a reservoir, and the open back pocket is not designed for it. On an ultra where aid stations are more than 15 km apart, this choice forces you either to live with the range of two flasks or to rig up a solution the brand never intended. It is the Sense Pro 6's most concrete limitation against competitors like the Oxsitis Gravity, designed from the start for both uses.

Pros and cons

Sense Pro 6 vs ADV Skin 5: the comparison to make the right choice

The two vests share a brand and part of their audience, but not the philosophy. The Sense Pro 6 bets on lightness and quick flask access, the ADV Skin 5 on versatility and storage.

Put simply, the Sense Pro 6 suits runners who want to go fast with the bare minimum. The ADV Skin 5, cheaper and more versatile for storage, remains the default choice if you want a single vest for every race format.

Sense Pro 6 vs Ultimate Direction Race Vest 6L and NNormal Race Vest 5L: the competitor comparison

On paper, the Sense Pro 6 is the lightest of the three. In practice, its two direct competitors offer a zipped back pocket that Salomon did not see fit to include, and Salomon still charges more. The short version: the Sense Pro 6 wins on fit and breathability, the UD Race Vest 6L and the NNormal Race Vest 5L win on secure storage and value for money.

How to fit the Sense Pro 6 into your RunMorph training plan

For a marathon build or a short trail build, the Sense Pro 6 works well on long runs where two flasks are enough. On the tougher training blocks of a RunMorph plan towards an ultra, plan on a bladder-compatible vest as well for outings where refuelling points are far apart, and keep the Sense Pro 6 for quality sessions and runs under five hours where its lightness really makes the difference.

RunMorph Coach verdict

The Sense Pro 6 delivers the best part of its promise: a fit you forget about, solid breathability and front pockets among the most practical on the market. But Salomon sacrificed rear storage and bladder compatibility on the altar of minimalism, and you pay for it as soon as you step outside short races with frequent aid stations. At 180 € for a 6-litre vest that can't carry a bladder, value for money is the openly weak point of this review. 7.8/10, for a vest that excels on its specific terrain and struggles outside it.

Key takeaways for your training

• 141 g claimed, 149 g measured: expect a real weight slightly above the spec sheet in size M or L.
• Two 500 ml flasks included: enough for up to about three hours of effort with regular refuelling.
• No bladder: plan on another vest if your long runs go beyond 15 km between water points.
• Optional Custom Quiver: essential if you plan to run with poles in this vest.
• 180 € at the official price: watch out for sales, the price regularly drops to around 135 €.
