So let's explore what to look for to protect yourself from unnecessary injuries and keep you from getting sidelined. 

Knee Sleeve Info & Buyer's Guide

What Is A Knee Sleeve?

A knee sleeve is worn around the knee and provides protection from injuries during complex movements. 

The knee sleeve can increase blood flow in the knee helping an athlete like you have maximum performance without incurring an injury. 

Still, don’t know how to get yourself a good knee sleeve?

Well, this article is meant to guide you through the entire process of choosing a perfect knee sleeve for you.

When to Use Knee Sleeves

Don’t know whether you need to wear knee sleeves in the first place?

Well, knee sleeves are basically used to prevent injuries when you engage in high intensity sports such as basketball, weightlifting, and athletics.

Overextending your knee will most definitely lead to an injury and thus you need a sleeve or brace to prevent this.

When you start increasing the amount of mass you lift, the more force goes to your knees, which is why sleeves are important. They can help protect against long-term knee injuries and save you from having to deal with more severe means of treatment like surgery.

For weightlifting, you don’t always need to use knee sleeves. If you're performing exercises that do not utilize the knee, they are not required. But I'd recommend that you use the right type of gloves for better grip, the best pair of lifting shoes - as well as a good set of lifting straps.

However, if you're performing squats, snatch, or any other knee-intensive movements, we recommend investing in a pair of knee sleeves and a pair of crossfit shoes to go with it.

Knee sleeves can also be worn by people with arthritis to prevent pain and inflammation in the knee joint. They prevent swelling and significantly reduce pain for arthritis patients.

Knee sleeves are also worn by people whose knees are recovering from a recent injury as they regulate the movement of the knee, hence preventing further injury. They quicken recovery time by restricting the range of motion and hence a person’s knee can heal faster.

Types of Knee Sleeves

If you are new to using knee sleeves, you might be having a lot of confusion over what type of knee sleeve to review and buy. The correct one will provide maximum protection and also prevent any injuries.

It will further improve blood flow in your knees during that next basketball game or workout where you are pushing your limits.

Depending on your need for a knee sleeve, there is a certain type which is perfect for you.

Whether you need a knee sleeve for athletics, weightlifting, simple workout, basketball, there is a specific knee sleeve that will match your needs. 

Pay Attention To The Thickness

There are basically three types of knee sleeves, which come in three measurements: 3mm, 5mm, and 7mm.

They are often made of neoprene or some other stretchable, padded material.

Each thickness has a different use case: 

  • 3mm – Lightest option and is more suited to endurance sports, as it provides that extra bit of support towards the end of your workout during lightweight activities like jogging and running.
  • 5mm – Gives you the support you need while remaining agile enough to perform a variety of movements during a WOD, sports, or other cross training. 
  • 7mm – Ideal for short and heavy activity and provides optimal support and stabilization for weightlifting. Proprioception is increased, giving you better awareness and allowing you to focus on form without fear of an unstable knee during heavy lifts. Also recommended when recovering from an injury.

For CrossFit, stick with products that are either 5mm or 7mm thick. 

Both thicknesses are capable of getting the job done and it will just come down to personal preference, as you might feel that 5mm is too light or 7mm is a bit too bulky.

Your best bet is to try them both! More tips on picking the right thickness here.

How Much Do Knee Sleeves Cost?

Before you make any purchase, check to see if it’s sold as a single sleeve or as a pair, as this can obviously impact the price point.

Expect to spend anywhere from $20 upwards to $80 per set depending on the brand, but many fall in the $40-50 range.

Our Verdict: Best Overall for Lifting & CrossFit

Nordic Lifting is a forerunner known for producing high-quality equipment with weightlifters in mind, and these knee sleeves are no exception.

Comprised of 100% neoprene, these offer the right amount of compression to encourage optimal performance and a therapeutic setting for a knee in recovery.

These are perfect for any heavy lifting workouts, including CrossFit and powerlifting.

2. Bear KompleX Knee Sleeves

Bear KompleX Knee Sleeves

Our Verdict: Best For Multiple Activities

Another good knee sleeve for ultimate protection during a range of activities is the Bear KompleX

This knee sleeve is available in both 5mm thick and 7mm thick measurements. It is a multipurpose sleeve meaning that you can use it for a wide range of sporting activities but it will still be excellent. 

The KompleX is made out of neoprene and offers extra strength, warmth, and support to your knees during that workout, weightlifting, and CrossFit WOD.

The KompleX Knee Sleeve is an all-rounder with no specific market target but rather a general approach towards its design.

This knee sleeve can be used by a lot of groups in the sports world ranging from weightlifters to wrestlers. You won’t have to worry about overdoing it in the ring or when lifting weights in the gym.

I would however not recommend the Bear KompleX to anyone who is involved in intense activities as it is not specifically tailored for such purposes. It is an all-rounder which means it has limitations in several aspects. It is still a good choice for people who engage in a variety of sporting activities.

3. PowerLix Compression Knee Sleeve

PowerLix Compression Knee Sleeve

Our Verdict: Best for Rehabilitation

The PowerLix is one of the best compression knee sleeves on the market. It is preferred by many athletes and weightlifters whose knees are going under rehabilitation. It offers the best compression you can find from a knee sleeve.

What makes PowerLix so unique is its ability to support the knee in both sport and rehabilitation.

With PowerLix, you can confidently engage your injured knee in light sports without having to worry about a recurrence of your injury. Its 3D-knitted design enables it to prevent the knee from swelling and also increases blood flow in the knee which is very crucial for a rehabilitating knee.

How does PowerLix manage to do all this? Well, the secret is in the design of the knee sleeve. PowerLix is made from high-quality neoprene which hardly tears.

It is also specially stitched in a way to provide maximum compression to the knee during rehab. The four-way compression design is one of the reasons why this knee sleeve is so excellent.

When in use, you will not feel like you are wearing anything so you will wear it for longer periods of time without sweating and feeling constriction on the knees.

You should, however, note that the PowerLix is a compression knee sleeve and it is therefore not suitable for people who are engaging in a maximum contact sport.

This is the best-looking knee sleeve you can find anywhere with an incredible design and amazing technology which is geared for optimum performance.

The design isn’t the only good thing about this sleeve.

The Nike Patella has a ventilated construction to allow the knee to breathe during a workout. This means you can put it on for a longer period of time compared to other knee sleeves I have selected. Furthermore, the sleeve is lightweight and will allow you to do your sports and other activities without feeling any excess pressure on the knees.

The airflow when using this knee sleeve is also amazing. It gives enough room for air to circulate the knees but still compresses any swelling you may develop during movement and also offers enhanced protection.

It is also equipped with a quick-drying feature which prevents sweat from accumulating in your knee during a workout. This means you won’t have to deal with a wet knee sleeve now and again when you work out.

You should, therefore, understand your needs before making a purchase and I am very certain that your experience with the use of knee sleeves will be a very good one.
