5/3/1 Athlete Knee Sleeves - Red/Blue

Limited remaining inventory: the Red/Blue colorway will not be restocked.

Built for training—not just for one heavy set. The 5/3/1 Athlete Knee Sleeves combine supportive 7 mm neoprene with enough comfort for a full lower-body session. The ribbed interior helps them stay in place through squats, lunges, trap-bar work, and high-rep weight-vest training. Sold as a pair.

The goal was simple: more support than a basic training sleeve without turning it into stiff competition gear. Athletes at London High School use these sleeves for squats, trap-bar work, and single-leg movements, while Jim uses them for high-rep weight-vest training. They are easy to put on and remove without assistance, comfortable enough for a full session, and praised for staying in place during high-volume, sweaty training.

How to Choose Your Size

Measure around the center of your knee with your leg straight, then use the size guide available in the product images. If you fall between sizes, choose the smaller size. Do not size down excessively for extra compression; an overly tight fit will reduce comfort and may accelerate wear.
