Three ways to teach your child. From beginner to little shredder

The MDXONE ”OX” is a snowboard/ski harness that combines

A kids backpack for your young student & a retractable leash for the instructor.


MDXONE “OX” has a 16 feet retractable red tape/cord with two 12” bungee cords at the end to connect to the Backpack/harness attachment points.

  • With the retractable leash, you can now decide the distance between you and your student with a simple push on the stop/release button with your thumb.
  • Let your child go on his/her own. Press the stop button to slow him/her down, prevent a front edge or make them turn.
  • When hitting the stop button, the bungee cord will extend slowly which will not cause a jarring effect on the student. No more playing human yo-yo with your child.
  • There’s no lock button on the leash, only a stop button.


  • MDXONE “OX” is a small backpack/ 5 points harness (10”H x 9”W x 2”D)

  • Optional/removable seat harness for extra support, especially for the little ones
  • Three attaching points for the Leash.
  • Chest and waist adjustable straps
  • You’ll also like the two grab handles.
