The Hirundos is a great, lightweight harness geared for sport climbers looking for their maximum range of movement. However, it is also very popular among alpine climbers because of its weight and quick-drying design. To sum up this harness in one word: skinny. The leg loops, waist belt, and belay loop are among the skinniest of all harnesses we tested.
If you are loyal to Petzl harnesses and want either a light sport climbing harness or an alpine harness, you will love this. If you want the absolute lightest harness for alpine routes, the Camp Air is 30 percent lighter. If you are looking for a high-performance sport climbing harness and can spend another the extra money, we recommend the Black Diamond Ozone. If you are considering this harness also look hard at the Petzl Sama, which is only a little heavier and much more comfortable and versatile.
