Black Diamond Run

Frequently Asked Questions

• How do Black Diamond Distance vests and Distance Packs differ, and which should I choose for fastpacking versus short, high-speed races?

  For short, high-output races the streamlined Distance 2/6 vests and Distance Belt prioritize minimal bounce, close-to-body storage, and rapid access to bottles and gels; they’re built to “disappear” on the body for fast efforts. Distance Packs (8L, 15L, 22L) use a lightweight body‑mapped harness and provide more capacity and organization for overnight fastpacks or peak bagging while still minimizing bounce.
• How should I size Black Diamond apparel like the Rhythm Tee or Alpine Start Hoody for trail running and layering?

  The Rhythm Tee has a slim, stretchy NuYarn construction so many runners size up if they plan to layer or prefer extra room; the Alpine Start Hoody and Liquid Point Shell are cut for freedom of movement with underarm gussets but fit close to avoid flapping under a pack. Check gender‑specific fits and match your size to the thickness of your base and midlayers—if you’ll wear insulated layers, opt for the next size.
• What materials and technologies give Black Diamond shells and jackets their balance of waterproofing and breathability?

  Black Diamond pairs BD.dry™ 3L stretch nylon and GORE‑TEX/softshell hybrids with a PFC‑free Empel DWR to deliver durable water resistance while maintaining stretch and mobility; BD.dry™ is specified around 20,000 mm / 20,000 g/m²/24hr for robust waterproof/breathable performance. Strategic features like diamond spacer mesh, underarm gussets, and perforated venting dump heat during high-output efforts without sacrificing protection.
• How do the Distance Carbon FKT poles compare to the Pursuit Carbon FLZ for mountain running and FKTs?

  Distance Carbon FKT poles are tuned for fastpackers and FKT attempts with a focus on lightweight construction and energy return, while the Pursuit Carbon FLZ adds rapid‑deploy convenience through a folding shaft and FLZ quick‑connect magnetic straps for fast stowage. Both use ergonomic cork grips and adjustable lengths for efficient force transfer; choose the FKT poles if marginal weight and rhythm matter most, or the FLZ if transition speed and compactness are a priority.
• What harness and pack features reduce bounce and pressure on long technical runs?

  Solution and Zone harnesses use Contour Edge shaping, a seamless Infinity Belay Loop, and widened gear loops to spread load and reduce pressure points, while Distance Packs feature body‑mapped harnesses and custom back panels that stabilize the load and promote airflow. Combined with soft‑edged stretch fabrics and gender‑specific fits, these design elements keep gear moving with your body to minimize bounce on technical terrain.
