In a trail pole market dominated by German and Austrian brands plus a handful of Scandinavian ones, TSL Outdoor stands out: made in Annecy and Allevard, the long-time snowshoe specialist has become a benchmark for premium folding poles in just a few seasons. The Trail Carbon 4 Shadow, with its patented magnetic gauntlet system, is its most polished proof yet. But at 170 euros a pair, can it really hold its own against the Leki and Black Diamond poles that have owned the podium for years?

TSL Outdoor: the snowshoe maker taking on trail poles
For 40 years, TSL has been THE French snowshoe brand. That positioning could have kept it stuck in winter hiking, but the Alpine company used its carbon expertise and machining know-how to move into trail poles, a segment where German (Leki) and Austrian (Komperdell) competitors have called the shots for decades. The Trail Carbon 4 Shadow is now showcased as the flagship product on the brand's official website, alongside a configurator that lets you customize the grip, strap and tip to suit how you use them.
The bet is clear: rather than chasing grams like the Leki Ultratrail FX.One Superlite, TSL relies on a patented magnetic gauntlet system designed to change the very way you handle a trail pole on the run.
RunMorph tip: if you're torn between durability and pure lightness, compare the Trail Carbon 4 Shadow with the Black Diamond Distance Carbon Z before you buy. Both poles target the same budget, but not the same trade-off.
Trail Carbon 4 Shadow specs: built for durability

| Feature | TSL Trail Carbon 4 Shadow |
| Brand | TSL Outdoor |
| Type | Folding trail pole, 4 detachable sections |
| Material | Carbon (16 / 14 / 14 / 14 mm tubes) |
| Weight (115 cm) | around 200 g per pole, Magnetic Cork grip |
| Folded length | 38 cm (Cork/Cork Cross grip) |
| Available sizes | 105 to 135 cm, in 5 cm increments |
| Grip | Cork (dual-material cork), Cork Cross or Ultra Mid EVA |

| Tip | Tungsten, Crossover tip with 8 studs included |
| Manufacturing | France, Alps (Annecy / Allevard) |

The detail that jumps out against the competition is weight: at 200 g per pole in the 115 cm size, the Trail Carbon 4 Shadow carries nearly 55 g more than the Black Diamond Distance Carbon Z or the Leki Superlite. TSL owns this choice. The brand favors generous-diameter carbon tubes and a build designed to last, not to break lightness records on a kitchen scale.
Magnetic System technology: the gauntlet that clips itself in

The real selling point of the Trail Carbon 4 Shadow is its Magnetic System ST gauntlet. Unlike a classic strap you have to slip on and adjust every time you grab the pole, this gauntlet attaches to the grip with a powerful magnet: just bring your hand close and the pole clips in on its own. To release, a simple press of your thumb on the button frees your hand, no two-handed fiddling required.
The grip itself comes in three versions: the Cork Cross (long, dual-material cork, designed for traversing side slopes), the Cork (short, same material) and the Ultra Mid (mid-length EVA foam). The included tip is the TSL-patented Crossover, whose 8 flexible studs deform on contact with the ground to grip without damaging trails or clattering on rocky sections. Underneath sits a classic tungsten tip for soft ground.
On the trail: from ultra prep to technical runs
At RunMorph, our analysis draws on several independent real-world tests of the Trail Carbon 4. They include an in-depth field test during preparation for a 110 km ultra-trail with major elevation gain (2,000 m of elevation gain per week for several weeks), backed by a series of verified user reviews that converge on an average score of 8.7/10.
One point comes up every time: the quality of the hold and the power transfer. One tester who logged several weeks of steep outings reports a very natural hold and efficient propulsion, to the point of picking these poles for a vertical kilometer, the most demanding event in trail running for pure force transfer. The magnetic clip system earns unanimous praise: no accidental unclipping reported, even under heavy use, and great freedom of movement on technical descents when the tester deliberately lets go of the poles, a technique close to ski touring.
Another tester, with several months of use at a body weight of 83 kg, confirms no deformation or play after prolonged use, which validates the choice of carbon tubes thicker than the market average.
Opinions clearly split on two points, though. First, weight: several testers used to lighter models (Leki, Black Diamond) notice perceptible inertia, especially on quick changes of direction or at a very high cadence. Second, the folding system: one full editorial review finds it a bit less smooth and less intuitive than the competition when unlocking the sections, while direct user feedback doesn't flag this flaw and mostly stresses how easy the gauntlet system is. For RunMorph, the trade-off looks clear: this pole is for runners who want durability and superior hand hold, not for those chasing grams on an ultra over 100 km.
TSL Trail Carbon 4 Shadow vs Black Diamond Distance Carbon Z: head to head
| Criterion | TSL Trail Carbon 4 Shadow | Black Diamond Distance Carbon Z |
| Weight per pole | around 200 g | around 145 g |
| Grip system | Removable magnetic gauntlet | Classic adjustable strap |
| Folding | 4 detachable sections, 38 cm folded | Z system, very compact |
| Tip | Tungsten + Crossover with 8 studs | Carbide + interchangeable basket |
| Manufacturing | France (Alps) | United States / Asia depending on range |
| Price | 150 to 170 euros | around 150 euros |
The Black Diamond Distance Carbon Z remains the lightness benchmark, with a weight gap you really feel on a long ultra-trail. But the TSL fights back with a faster grip system that feels more secure under heavy use, and a selling point Black Diamond can't claim: traceable French manufacturing in the Alps, with spare parts available for five years. Against the Leki Ultratrail FX.One Superlite, the gap is similar: Leki stays ahead on pure weight, while TSL takes back the lead with its original hold system.
Pros and cons

Pros- Magnetic gauntlet unique on the market, instant clip-in without aiming
- Durability confirmed over several months of intensive testing, with no play or deformation
- Power transfer and hold rated as very natural on steep climbs
- Traceable French manufacturing, 2-year warranty and spare parts for 5 years
- Versatile Crossover tip, quiet and gentle on trails
Cons- Around 55 g more per pole than the lightest models on the market
- Folding system rated a bit less smooth than a classic push-button
- The gauntlet's ball tends to clip itself back in when it touches the magnet
- Premium price (up to 170 euros) in a highly competitive segment
Our field verdict: who is it for?
The Trail Carbon 4 Shadow is for trail runners who put flawless hand hold and bombproof durability first on long, steep outings, rather than those chasing every tenth of a gram. The magnetic gauntlet system really changes how you release and reattach your poles on the run, a real plus on technical sections where you switch between free hands and pole support. On the other hand, an ultra runner targeting a race over 100 km, where every gram adds up over the hours, is better off looking at the lightest models on the market.
Pair it with your RunMorph plan
To make your long mountain runs safer or prepare for a trail race with major elevation gain, the Trail Carbon 4 Shadow fits naturally into a RunMorph training plan focused on elevation gain and trail-specific strength work.
RunMorph Coach verdict
The TSL Trail Carbon 4 Shadow will never win a lightness contest against the German and Austrian benchmarks. But it makes up for it with a truly distinctive magnetic gauntlet system, durability proven over time and a selling point few competitors can claim: French manufacturing in the Alps, backed and repairable for five years. 7.5/10 for a pole that fully owns its trade-off: a little heavier, much more reassuring in the hand.
