A climbing harness is an essential piece of climbing equipment, so choosing the right one is important. Most climbing harnesses have the same basic parts: a padded waist belt with locking buckles, two leg loops, a tie-in or belay loop, and gear loops at the sides. Some harnesses are versatile enough for all types of climbing, while others are made specifically for particular types of climbing. The type of climbing you do will determine which harness is best.
