For top-roping, in addition to climbing shoes, chalk, and comfortable clothes, you’ll also need a climbing harness, locking carabiner, and a belay device. If you’re climbing outside, a helmet designed specifically for climbing is essential. Climbing Harness: Your harness allows you to tie into the rope securely. Most harnesses have two front tie-in points designed specifically for threading the rope and tying in, one at the waist and one at the leg loops. Generally, the tie-in points are different from the dedicated belay loop. Buckling your harness correctly is essential.
