The ultra-light Nineteen G carabiners with H-profile construction ensure optimal material utilization at minimal weight, and a high-strength 11 mm Dyneema express sling can significantly reduce the weight of the gear. A lightweight wire gate on the lower carabiner reduces the risk of the whip-lash effect.
