A climbing harness is a safety device worn by climbers to secure themselves to a rope or other safety equipment. It typically consists of a padded waist belt and leg loops, which help distribute weight evenly and provide comfort during climbs. Harnesses are essential for both rock climbing and mountaineering, as they prevent falls and allow for safe movement on various terrains. Climbing harnesses come in different styles, including sport climbing, trad climbing, and alpine climbing harnesses, each designed for specific activities. They are usually made from durable materials like nylon and feature adjustable straps for a snug fit. Proper use and fitting of a harness are crucial for safety in climbing activities.
