The Camp JASPER CR4 is a harness suitable for mountaineering, the big wall. It has a wider belt than normal climbing harnesses with double adjustment at the waist in extra strong fabric. The 2 quick self-locking belt buckles allow for quick and perfect centering. The leg strap adjustment straps are retractable. The service ring measures 20 mm and is equipped with a patented No-Twist system. All the buckles are in steel, with a special design with differentiated thicknesses that facilitates their use. The 4 gear holders are extremely functional: the front ones are shaped to facilitate attachment and release of the equipment while the rear ones are more flexible and compact. The Hub slots have been further improved: higher and stronger, they ensure great stability to the special carabiners for nails and ice tools.
