10.6 PMI® Gym Pro is a top choice for climbing gyms, schools, guides and other situations where it will see some heavy use. It has a 22% thicker sheath than most other PMI Dynamic™ ropes, providing superior protection from dirt and wear over time. Although it is a top choice for gyms, this versatile rope is also rated for lead climbing under UIAA standards, so you can take it with you wherever you go!
