Sore muscles, joints & tendons rejoice! KT Tape Pro will relieve pain & provide support for up to 7 days through multiple demanding workouts. This athletic tape is the world's first 100% synthetic kinesiology tape, re-engineered with long-lasting adhesive & is used by USA athletes in all Olympic Training Centers. Synthetic performance fibers provide superior strength, stretch, & recoil. KT Tape Pro also features an adhesive formulated to remain in place for 4 to 7 days. KT Tape Pro fibers feature a stronger elastic core which delivers better support for muscles, joints & tendons without restricting comfort & range of motion. This improved elastic core retains its elasticity far better over time & provides more durable support than cotton kinesiology tape, lasting as long as you need it. Like top athletes, it relies on both strength & endurance to get the job done. KT Tape Pro is pre-cut & ready to apply right out of the box. Pre-cut strips have rounded corners which help to prevent the corners from catching on clothing or the edges fraying. Each roll contains 20 pre-cut strips that are 10 inches long & 2 inches wide.
