Unsure? Size guide



The Assassins are the latest generation knee sleeves from RockTape. The RockTape Assassin Knee Sleeves are your secret weapon to add more weight on your lifts and slashing seconds off your workouts. 

High repetition movements such as squats and pistols during your workouts and heavy lifting sessions mean your knees take a huge impact.

Assassins can be used in a variety of sports and fitness pursuits, including: weightlifting, high-intensity interval training, obstacle course racing, running, cycling and other functional fitness endeavours. 

When you are training hard, you need to ensure you have the quality support where it matters.


  • Longer in length delivering additional compression, warmth, stability and blood flow
  • Super durable utilising the latest in stitching technology
  • Protect the knee from abrasions during lunges or obstacle course racing
  • SBR Neoprene - a higher grade and more durable (90% neoprene / 10% nylon)
  • Provide VMO (vastus medialis oblique) support
  • Stay put with a unique organic design, won’t slip down during activity
  • Heat sealing seams ensure optimal comfort, tracking and a countered fit to your knee
  • 4-way Lycra liner provides a softer feel and better breathability
  • 12 Month Warranty
  • Available in 2 Thicknesses - 5mm or 7mm
  • Sold as a pair (two knee sleeves per package)

    Do I select 5mm or 7mm?

    5mm:  Knee support that won’t greatly reduce your range of motion and mobility. Good for metabolic conditioning and general workouts.

    7mm: A slightly more heavy-duty knee sleeve that delivers extra support for powerlifters, Olympic lifters, Strongmen, etc.

    Size Guide:

    For sizing, measure the circumference of your leg around the centre of your patella.

    A printable TWL Ruler is available to be downloaded here.

    The WOD Life Tip: If you are on the edge of the sizes, we recommend you go up a size as the Knee Caps fit tighter than a Rehband knee sleeve.

    Great quality

    Amazing quality but do fit quite tight,depending on how much compression you like in future I’ll aim for a size up.

    Really good support and good rebound at the bottom of the squat, feel a lot more confident with these on. Ordered an XL for my size and it maybe doesn't feel as tight as I'd like but still really rate them

    Do yourself a favour

    I've struggled with weak knees for as long as I remember. Using these sleeves had given me the confidence and support I needed to progress my training

    Long overdue purchase

    First pair of knee sleeves I’ve ever purchased, can’t believe I didn’t buy them sooner. Give me the extra support I need to lift heavier, also helped me get my first pistols as I don’t have the best knee stability. They run true to size, just need to take into account your calves (which if you’re like me they’re hard to get over), but otherwise super happy!

    Good support

    Good knee support, start to slip down during wods if I wear them with long tights. Can feel the difference with my knee injury when training without them. I got the 5mm and still have enough mobilty to do box jumps etc with
