The BEAL Booster III is not just any rope. With its smooth 9.7 mm diameter, it runs reliably through all belay devices. Whether it's a Grigri, ATC, or Megajul, this single rope is the ideal companion for climbing trips. It doesn't matter if you're tackling sport climbing routes in the limestone of southern France or in alpine terrain. This rope is a lightweight and robust sport climbing rope with top-notch features and impregnation, designed for experienced climbers. BEAL manufactures this rope using UNICORE technology, which firmly bonds the sheath and core during the weaving process. This eliminates sheath slippage and provides the rope with not only long-lasting smoothness but also an enormous safety reserve in case of sheath damage, which can occur from rock and ice falls or falls over sharp edges. The Booster has no limits in its application area and feels equally at home on rock and ice. With its high sheath percentage, it is also suitable for top roping and, of course, for extensive bouldering of routes.
