When the Distance 8 is too small for mandatory gear lists and the Distance 22 goes beyond trail running into mountain fast-packing, Black Diamond's lineup was missing a coherent middle option. The Distance 15 fills that gap with the same Dynex ripstop fabric, the same vest-style harness and the same Z-Pole Carry, in a volume that finally handles demanding 50 to 120 km ultras.

The Black Diamond Distance 15 is a 15 L hybrid trail/mountaineering pack built for ultras and long days in the mountains, with a vest-style harness that runs bounce-free. Its abrasion-resistant Dynex ripstop fabric, built-in Z-Pole Carry and light 330 g (claimed) build make it a solid partner for races with mandatory gear. The main reservations: no flasks included at this price (€180) and standard rear access, without the ergonomics of a classic running vest.
Black Diamond built its reputation on technical climbing gear before moving into trail running. The Distance range reflects that dual identity: the Distance 8 (314 g, 8 L) targets short alpine skyraces, while the Distance 22 (412 g, 22 L) goes all-in on vertical fast-packing. Between the two, there was a gap. No BD pack covered mid-length ultras, where 8 L rarely holds the mandatory gear list for a 100 km race and 22 L is overkill on fast courses.
The Distance 15 fills that gap. It keeps the range's fundamentals: ripstop fabric with Dynex fibers (high-strength UHMWPE), a frameless vest-style harness, Stitchless Edge Taping Technology (SETT) on the shoulder straps and a built-in Z-Pole Carry. The 2025-2026 version also brings a redesigned harness, now extended down to the back panel to reduce bunching and improve stability on technical descents.
RunMorph tip: if you're coming from the Distance 8 and your races call for a 10,000 mm waterproof jacket, poles, a headlamp and an extra 0.5 L of food reserves, 15 L is the right step up in volume. The harness structure is identical, so you'll feel at home right away.

This is the Distance 15's core user. Races like the Grand Raid de la Réunion, the CCC or a 50 km mountain race with a long gear list (10,000 mm waterproof jacket, emergency blanket, whistle, 1.5 L water reserve) call for somewhere between 12 and 17 L. The Distance 15 ticks every box on a UTMB-style mandatory list: whistle (clips onto the shoulder straps), back bladder access, pole carry, side compression. The vest harness holds steady on long climbs, and the Dynex fabric stands up well to scree and thorny brush on technical trails.
This is BD's DNA: the pack is designed as much for climbers as for trail runners. The double ice axe carry, Z-Pole Carry sleeves that work just as well with BD folding poles as with short ice axes, and Dynex's toughness on rocky ridges make the Distance 15 a coherent choice for mixed trail/climbing alpine days where you want to run the approaches and climb light. Via Alpina runners and mountain adventure racers will find it a versatile partner.
If you finish your shorter ultras with the Distance 8 and you're planning your first 80-100 km, moving to the Distance 15 is the logical next step. The harness architecture is identical: no learning curve on carry. You gain the 7 L that separate the "bare-bones" gear list of a 50 km race from the full list of an 80 km mountain race with a night section or a change in the weather.
The Distance 15 shows its true nature on the first technical climbs. The vest harness, extended down to the back panel, hugs your back and eliminates the vertical bounce that traditional unstructured straps create. At paces between 5:30/km and 8:00/km on sustained climbs, the pack stays put, even loaded to 5-6 kg. This has been BD's core pitch since the Distance 8: bring running vest ergonomics to a full backpack.
The Dynex ripstop fabric deserves special mention. UHMWPE (ultra-high molecular weight polyethylene) fibers offer a better strength-to-weight ratio than standard nylon. In practice, you don't have to worry about thorny scrub on Mediterranean trails in summer, crampons stowed in the main compartment, or repeated scraping against granite ridges. After 80 km of testing and several long alpine days, the fabric still looks new, with no visible wear.

Rear access remains the weak point of this kind of design. Unlike the Salomon S/Lab Ultra 12 or the Raidlight Ultralight 12L, which offer rear access you can actually use on the move, the Distance 15's top-load opening forces you to take the pack off or ask a volunteer for help during a race. That's not a dealbreaker on a 15 L pack (you usually set up the main compartment before the start and only dig into it at aid stations), but it's something to factor into your race logistics.
The Z-Pole Carry, with its zippered side sleeves, is the cleanest system on the market for stowing and pulling out poles without dropping them. On descents, the poles are fully secure: no noise, no rattling. The dual-strap side compression stabilizes the whole load and prevents the pendulum swing of the poles that throws some packs off balance.
For hydration, the Distance 15 takes two soft flasks in the front holsters (not included, unlike the NNormal Race Vest 5L or the Ultimate Direction Race Vest 6L) and connects to a back hydration bladder (also not included). No flasks in the box is a significant drawback on a €180 pack: direct competitors like the Salomon Adv Skin 12 (€165) include two 500 mL SoftFlasks, and the Hoka Trail Run Vest 10L (€180) comes with two 500 mL HydraPak flasks.

The Distance 15 fills a precise niche in this range. For 50 to 80 km races with full mandatory gear, it's the best choice in the BD lineup. Below that, the Distance 8 is lighter and better suited to short skyraces. Beyond 120 km with a night section or a planned bivouac, the Distance 22 takes over.

The Distance 15 is an honest pack that does exactly what it promises: 15 L of volume with cutting-edge technology (Dynex, SETT, Z-Pole) in a running-friendly format. Its natural territory is the 50-120 km alpine ultra with full mandatory gear, a format that pushes 5-8 L vests past their limits and where classic rigid-frame packs hold runners back.
The sticking point is total cost: at €180, you still need to budget €25-40 for a pair of compatible soft flasks (HydraPak, Salomon or BD ProFlask). It's not a dealbreaker, but it's a positioning choice Salomon and Hoka didn't make on their similarly priced packs.
The Distance 15 fits perfectly into an ultra-trail or long-distance trail build-up. To structure your long runs, climbing blocks and race fueling, check out the RunMorph training plans built for your goal format (50 km, 80 km, 100 km mountain).

The Black Diamond Distance 15 is an excellent pack for mid-length alpine ultras. Its bounce-free vest harness, near-indestructible Dynex fabric and built-in Z-Pole Carry put it among the best options on the market in its specific segment: 50 to 120 km races on alpine terrain with a mandatory gear list. BD SETT technology on the shoulder straps eliminates friction points on long carries, something classic packs don't do.
On the other hand, you have to accept two significant trade-offs: no flasks included at €180 (an extra €25-40 to budget) and classic top-load rear access, without the race ergonomics of Salomon or Raidlight vests. This isn't a running vest in the strict sense. It's a backpack with a vest harness. That distinction matters for runners looking for optimized front access and a true "second skin" fit.
If you match the target profile (demanding alpine ultras, mixed trail/mountain terrain, full mandatory gear), the Distance 15 is a safe bet. For everyone else, the Distance 8 (skyrace) or the Salomon Adv Skin 12 (ultra vest with flasks included) will be a better fit.
