Based on miscommunication and misinterpretations from both sides (IPF as well as SlingShot), both parties agreed to remove the SlingShot X Knee Sleeves with the non-slip grip on the inside of the sleeves from the IPF approved list 2019-22.
SlingShot will produce a version of X Knee Sleeves without the non-slip grip on the inside of the sleeves, which will be IPF approved and listed on the IPF approval list 2019-22.
