An adjustable footloop to facilitate ascending with an ascender or handled ascender
 
Quick tightening footloop.
The AIR STEP footloop has a quick release ON-OFF system. In the ON position, the foot is securely held in the loop. In the OFF position, the system does not hinder the user if he wishes to move his foot. Tightening is facilitated by a large easy to grasp buckle, usable even with gloves. Moreover, a rigid reinforcement makes it easier to insert your foot.
And last but not least, a webbing reinforcement makes the system more resistant to abrasion.
