Arbsession Turbo Knee Ascender

$144.95

Built by the Arbsession Splicing Dept. this knee ascender is best when paired with a set up like the DMM Tendon. Where the bungee is built into either the climbing harness or chest harness. 

This knee ascender is not a new concept. Many have made their own. We just wanted to offer it to the climbers that just want to get one and climb. 

Please allow additional time as these are spliced to order and require the naked eye to be dipped and cured.
