Black Diamond Solution is the standard sport climbing harness for intermediate to advanced climbers. We looked at how it compares to Petzl Hirundos for long climbing days.
Who it's for
Buy this if: Sport climbers and gym climbers who need an all-day comfortable harness at a reasonable weight.
Skip this if: Alpine climbers who need a harness that fits over thick insulation layers — the fixed adjustment doesn't accommodate bulky layers.
In practice
Fusion Padding
Traditional harness padding uses solid foam — comfortable but bulky. Fusion's waffle pattern removes material in zones where pressure is lowest, concentrating foam where hip and leg contact is heaviest. The result: same comfort, 20% less material, meaningfully lighter.
