We recommend sizing based on thigh measurement, not height or weight alone.

1. Use a soft tape measure around the thickest part of your thigh (on the leg that will wear the sleeve).
   
2. Match that number with our size chart.
   
3. If you’re between two sizes:
   
   
   choose the smaller size for a tighter, more supportive fit
   
   
   choose the larger size for a lighter, less tight feel
   
   
   

The sleeve should feel like a second skin: snug and supportive, but not painful or cutting off circulation.

This is one of the main problems we wanted to solve.

DunkFlex uses:

• an inner anti-slip band at the top
  
• a second-skin compression fit around the thigh
  

As long as you pick the right size, the sleeve is designed to stay in place during cuts, jumps, and landings – not roll or slide down every few minutes like many generic sleeves.

We’ll be honest: no sleeve can magically cure an injury.

What DunkFlex is designed to do is:

• support the knee joint and surrounding tissues
  
• help keep the leg more aligned and “locked in” on movement
  
• help reduce stress and vibration on the knee
  
• help your legs feel less wrecked during and after playing
  

Many hoopers with ACL history, meniscus issues, jumper’s knee or “old man knees” report less pain and more confidence when they play with DunkFlex compared to playing with no support or basic sleeves.

It’s not a medical treatment – it’s real, functional support built for basketball.

No.

Most generic sleeves are made for walking, light fitness or everyday use.

DunkFlex was created by pro hooper Elijah Tshibangu and developed with:

• pro and high-level players in Europe
  
• physios, strength coaches and textile specialists
  

It’s built around basketball movements (cuts, jumps, landings, defense stance) with:

• smart compression that wraps thigh, knee and upper shin
  
• a locked-in feeling on the court
  
• real anti-slip grip
  
• a design tested in actual games and runs, not just in a catalog.
  

No – that's exactly what we wanted to avoid.
DunkFlex is designed to give you support without stiffness:

* no bulky hinges
* no rigid straps
* flexible knit that moves with your leg

You can still:

* run at full speed
* squat, lunge, and lift heavy
* sprint, cut, and jump

Most athletes say they forget they're wearing it once the session starts, except their knee feels more secure.

A cheap sleeve can be okay for walking or light activity. Real training puts way more demand on your knees:

* repeated impact and pounding
* sudden direction changes
* hard landings, sprints, and heavy lifts

DunkFlex costs more because it's:

* built specifically for serious athletes
* designed to actually stay in place when you sweat
* engineered to support thigh–knee–shin as one system

If you train regularly and your knees matter to you, it's not "just another sleeve" – it's an investment in your ability to keep performing longer and more comfortably.

DunkFlex is used by athletes with:

* past ACL injuries
* meniscus tears or surgeries
* runner's knee / patellar tendon pain
* early arthritis / "old knees"
* general instability or discomfort

It's designed to provide extra support and comfort, not to replace medical treatment. If you have a serious condition or recent surgery, you should always follow your doctor or physio's advice first. You can then use DunkFlex as additional support if they approve it.

DunkFlex is a compression product, so it's normal for it to feel snug. But it should not be:

* painfully tight
* cutting into your skin
* causing numbness

The fabric is breathable and soft inside, designed for long sessions and intense workouts. If you feel discomfort, you may need a different size.

You have 60 days to try your DunkFlex sleeves.

If you don’t like them for any reason, you can send them back within 60 days and we’ll refund you
