Knee sleeves add warmth and compression, aiding in pain relief by increasing blood flow + reducing swelling during and after your workouts allowing you to recover faster from your training.


Knee sleeves add stability to your lifts by creating kinetic awareness and limiting patellar movement. Sleeves provide your body awareness, cueing for your knees and neighboring parts of the body keeping you in a better position during a lift.


Maximize your training by adding knee sleeves to your leg day routine. The compression knee sleeves provide allows you to stack weights and rebound harder out of the hole under maximal weights.


Let’s face it, we all want to be as agile and active for as long as possible. Longevity is key. Adding compression and warmth to your knees helps take the stress away from the joints, allowing you to get more blood flow + recover faster, keeping you healthy + STrong.


Added stability and rebound out of the hole in combination with consistency creates confidence under tension. Build confidence under maximal weights knowing your knee sleeves can keep you protected + pain free.


Here at Sling Shot®, we are always pushing the envelope. After the success of our versatile Sling Shot® Knee Sleeves, we sought to create new knee sleeves aimed directly at strength athletes. We tirelessly tested prototypes with our own Super Training Team and top lifters like Stan Efferding and Brian Shaw during their biggest lifts. Countless revisions later we finally had what we were looking for, the best competition knee sleeves money can buy, the Strong Knee Sleeves.


How do I know what size I am?

You can find out what size you are by measuring the circumference of the center of your knee cap at full extension in inches. Then refer to the suggest size chart. Keep in mind, if you have larger calves, we recommend sizing up one.

What’s the difference between competition fit and comfort fit?

Comfort fit means you can wear the sleeve for your whole workout where competition fit means you can only wear them on for a set at a time (you might want to roll them down between lifts). When you’re deciding which sleeve size is best for you, take into consideration the size of your calves. If they are larger than your knee, size up.

I have a size 16” knee, should I go with the L, XL or 2XL?

If you’re looking for comfort fit, you would want to go with L if you’re looking for competition fit you will want to with the XL. If you have larger calves, you will want to size up.

Are the sleeves sold as a pair or individually?

Our sleeves are sold as a pair 😊

Can I compete in these?

Yep! Our Strong Knee Sleeves are guaranteed to not exceed 7mm which is the standard for most federation guidelines. We recommend double checking with the federation just in case.

How do these compare to the X Sleeves? What about the Gangsta Knee Sleeves?

The Strong knee sleeves provide 7mm of support with a two way stretch and a single seam for medium to heavy lifting. These sleeves are USPA and IPF approved for 2019. The Extreme X Sleeves have ZERO stretch and are best for heavy lifting and are IPF and USPA approved for 2019. Lastly, the Gangsta Knee Sleeves are 9.5mm thick with a two way stretch THICC as ever and are NOT federation approved.

How do I wash my knee sleeves?

We recommend hand washing in cold water with mild detergent and air dry to complete. We do not recommend putting our sleeves in a washing or drying machine this will void the warranty. Pro tip – After your workout session make sure you turn your sleeves inside out and leave them outside of your bag to dry.

If I want a tight fit, should I size down?

We recommend considering our suggested size chart. If you would like a tight fit, I recommend going with competition fit.

When should I use my knee sleeves?

The STrong Knee Sleeves can be used during any movement where the knees need support, compression or protection. Movements like Skwaats, Leg Press, Hack Skwaats, Lunges, etc are all great examples of when the STrong Knee Sleeves will help.
