    $154.99
    In stock

    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.

    This is a super nice piece of kit. I am running it with the DMM tendon and it does a great job of advancing up the rope. I get full steps every time!

    Awesome

    So I've recently switched over to this knee ascender from the SAKA and I couldn't be more pleased with it. In my opinion the SAKA is the best stand alone system hands down, but I've recently switched saddles to the Tree Rex 2.0 and it has the built in bungees on the hips making the self Advancing bungee obsolete for my system. This thing is super well put together and has to be the best splicing I've ever seen. The camp ascender is tough and super well designed. If you're running a system with its own bungee in the chest harness or saddle and running climb boots with built-in attachment points this knee ascender is where it's at. Super big props to the splice department, I'm pretty sure they did some sort of voodoo magic and like wrapped a chunk of 8mm bee line in some other Ropes jacket did all the BOSS-ASS twists and turns and locked it all in with some very pretty heat shrink. You for sure want this, so stop looking around and buy it.
