As a climber, your hands and fingers get shoved into cracks, scraped on rock, tweaked on tiny holds, and dried out with chalk, so it makes sense to look after them. Using Fingertape can help to support finger injuries. It can even be used to support sore wrists or elbows. Of course climbing with an injury is not a good idea, but if it's more of a niggle than something worse, some fingertape carefully wrapped around you finger can really help. Various thicknesses are available.
