Friction Labs Climbskin File
Friction Labs Climbskin File, An often looked-over practice is filing calluses to prevent pulling off flappers while pulling hard moves. With Friction Labs' Climbskin File, you'll have the perfect tool to keep you calluses from getting crazy out of control. Once you start to shed just enough skin on your calluses that you can feel it snag on your clothes, take the Climbskin File to them and rub them down until they're once again soft. This helps build up skin so you can climb longer on your hard-earned calluses without losing them.
