The Black Diamond Solution is the most comfortable harness that we have ever worn. Since our harness ratings are especially heavy on comfort — accounting for 70% of a product's final score when combining comfort while standing, hanging, and belaying — it is no surprise that the Solution was among the highest scoring harnesses in our review. While it doesn't have the absolute widest or most heavily padded waist and leg loops, the Fusion Core Construction disperses a person's weight in a way that was simply unrivaled among its competition. Despite this praise, the Solution will not be the optimal choice for everyone, as its design and feature set are targeted specifically toward sport and gym climbing, eschewing many convenient and necessary features for carrying a large rack or extras up long trad climbs. For this reason, we called it our Best Harness for Sport and Gym climbing, and for these disciplines, don't think you could find a better option.
Black Diamond has freshened up the Solution harness for 2018 with some new color options. It now comes in the black and blue version shown above, as well as the all-black version with bright yellow belay loop that we reviewed.
