The Evolution series started it all back in 1993 with Sterling's release of the first 10.2mm instead of the standard 10.5mm. The sheath and core construction of Evolution ropes are engineered for the ideal balance of low impact force, lightweight, and high fall ratings, all of which make these climbing ropes incredibly durable. The smooth sheath produces less drag through gear and over rock, allowing for an easier clip. Tested worldwide under extreme conditions, these ropes continue to prove to be the right rope for any climb.
AERO 9.2mm TM
Fast and light as a feather, the Aero is a skinny 9.2mm rope with smooth and handling. Sterlings lightest weight single rope in the Evolution Series, the Aero balances a durable, tough sheath with a new lighter weight core construction. The result is a sending rope with softer handling. Ideal for sport climbing, mixed climbing and ice climbing.
