Black Diamond’s Distance 4 Hydration Vest is a streamlined trail running vest for long-distance, fast-paced efforts. After months of testing, GearJunkie approves the pack for lengthy mountain runs and scrambles. Read on for a review of the Distance 4 Hydration Vest.
Black Diamond is a forerunner in climb and ski equipment, but the brand is expanding gear for trail running adventures. Introduced in the spring, the 2020 Distance 4 Hydration Vest is a comfortable pack for trails and scrambles in mountainous terrain. The 4L pack is an extension of the 2019 Distance collection, which includes 8L and 15L backpacks for mountain running.
In short: The Distance 4 Hydration Vest is a lightweight, stretchy, and durable pack with innovative storage solutions. The airy vest offers ample space to tow apparel, nutrition, hydration, and gear. The vest worked well for short, daily trail runs and also for ventures with stout mileage in a single push.
Distance 4 Hydration Vest Review
Typically, I favor women’s-specific trail running packs due to the tailored fit and shape. I was surprised that this gender-neutral vest hit the mark.
I tested a size medium, which has a torso circumference of 80-100 cm. (Note: Measure around the lower ribs.) I liked a roomier size. Due to strap adjustments, the pack never felt too tight and never swung around. The vest offers four size options:
- XS: 60-75 cm
- S: 68-85 cm
- M: 80-100 cm
- L: 90-122 cm
For several months, I tested the vest on high-altitude adventures in Colorado’s Elk Mountains. It felt secure while climbing on granite formations between trails in Hartman Rocks Recreation Area. I also took it on a scramble up the iconic Avery Red Diamond: a 2,000-foot sheer, solid rock face. The 6.5-mile route features a 3,200-foot ascent that reaches 12,600 feet, so I needed extra gear despite the relatively short distance.
