How To Choose What Size Harris COMP MAX Knee Sleeves You Need?

Measure Your Knee Circumference

With a straight leg, use a flexible measuring tape to determine the circumference of your knee at its widest point. Ensure the measuring tape fits snugly.

Determine Your Size

Harris COMP MAX Knee Sleeves are available in various sizes, ranging from small to 3XL. Refer to the size chart to find the suitable size based on your knee circumference measurement. Select the size that aligns with your measurements best, ideally within the OPTIMAL fit range.

Consider Your Preference

Harris Comp Max Knee Sleeves provide a STIFF and VERRY TIGHT fit due to the proprietary ultra-dense neoprene matrix. Be aware that even if your measurement falls within the OPTIMAL rang the sleeves will still be very hard to get on and off.

Please also consider when choosing your size these four things:

  1. If your calf is bigger than your knee joint make sure the size you choice has a maximum size equal to or bigger than your calf. Otherwise when fitting you won’t get the sleeve on over your calf.

  2. If you have larger then normal quads you may need to size up to accommodate the extra muscle mass.

  3. When you are training or competing in the knee sleeves your muscles will swell with blood and can make it more difficult to take them off.

  4. If you prefer a slightly looser fit, you can opt for a size up.

  5. If in between two sizes or just in doubt it is advised to allways size up.

Maximum Performance

If you are chasing the tightest fit possible and maximum compression, we suggest not sizing down past the maximum tightest fit of a chosen size. Please also note if you are wearing these sleeves too tight and undersize by choice or by acident, this will push the neoprene beyond its capability and there is a chance of the meterial failing. Like any material there are tensile limits. Going beyond this may result in failure, such failure is not covered under warranty as this has resulted from missuse.

Eg. If your measurement is 40cm we suggest you do not try and fit into a size medium with a maximum of 39cm as you will find it extremely hard if not impossible to get them on and you may have little chance to get them off. Also sizing down may result it structural failure. 

Please also note that when using the tightest fit possible for performance you will need help getting the sleeves on and off by an experienced team mate or coach. Not for the faint hearted, you have been warned! Undersizing will void any warranty.

! Warning !

If at any stage you feel that the sleeves are going to be too tight do not proceed. It is your responsibility to follow the recomended guidelines and prioritise your safety.


Fitting Guide

When you get your sleeves try them on

Once you receive your knee sleeves, carefully put them on one leg at a time, remember it is best to become proficient at putting the sleeves on and off before attempting in a lifting environment.

Use the following method to get the sleeves into position:

  1. Ensure that the logo or branding on the sleeve faces forward and the seam is to the rear.

  2. Fold the top of the sleeve inside out onto itself in half. Because the sleeves are so stiff you will only be able to do this a small part at a time, continue until the sleeve is in half.

  3. Put your foot through the sleeve and then pull over the heal of your foot and centre the sleeve again.

  4. Use your fingers to hook under the bottom of the sleeve, between the sleeve and your calf and pull the sleeve up as high as you can so that the top fold of the sleeve reaches just above the centre line of the knee joint.

  5. Gently roll out the top of the sleeve over your quad and even out any creases to get a form fit.

  6. If the knee sleeve isn’t sitting high enough roll back down the top of the sleeve and repeat instructions 4 & 5.

You can further improve on the above fitting instruction by the assistance of the following:

  1. Before putting the sleeve on have a full length deadlift sock on your foot and leg all the way up to your knee. The better fitting the sock is without any creases or wrinkles will make sliding the sleeve up into position easier.

NOTE:The use of lifting straps looped inside the sleeve is not reccomended as this can lead to excessive stress on the neoprene. This will void warranty.

Assess Your Fit

The knee sleeve should fit firm, snugly and offer unparalleled compression around your knee joint and quad. Just like using heavy knee wraps for the first time you can expect a small amount of discomfort depending on the level of tightness and compression you have chosen. It should stay firmly in place without sliding down or bunching up during activity.

Test Functionality

Perform a few movements, such as squats or lunges, to verify that the knee sleeves provide the desired support and stability. Evaluate comfort and performance by paying attention to how the knee sleeves feel during your training or activities.

Remember that individual preferences may vary, and it's important to find the right balance of compression, comfort, and functionality. If you are uncertain about the fit or experience any discomfort, it is recommended to consult the above fitting guidelines or seek assistance from a knowledgeable professional.

Comp Max Knee Sleeves

Purchased these for an upcoming comp, and can I say they deliver! Hit a sleeved PB in comp. Heed the warnings, and definitely take your time in sizing - these are super stiff, I mean cast-like levels of stiffness. There is a trick to getting them on, and then off again, but worth the effort.

The price of these sleeves does not reflect the quality and performance ability, in my opinion. I am here for it and you should be too.
