Hi, My Name is Jeremy Campbell, I am a doctor of physical therapy and former Marine Corps Veteran and today I want to show you

Why The Knee Flex Pro™ Is My Favorite Tool For Getting Patients Up And Moving Without Pain.

I have dedicated my life into helping myself (and others) get up and moving without pain, so I created the original COCOON Knee Flex Pro - I wish I had this after my accident. It would have made my recovery so much easier!"


Every knee pain sufferer knows that knee pain comes with the ultimate catch-22. On one hand you have to keep moving to keep your joint from getting stiff and sore…. But on the other hand, every time you move you’re in pain! It’s enough to drive you mad, but the truth is… 

Too Much Rest = More Knee Pain

Too Much Rest = More Knee Pain

It sounds crazy but it's true! And I’ve learned this lesson the hard way...

Long before COCOON was founded, I served in the Marine Corps and had a very successful career — first as a Machine Gunner, and then as a Doctor of Physical Therapy.


I began my service in the Marine Corps in mid 1990s. Manning the machine gun turret on those big Humvee trucks you see in the movies.


I was involved in a vehicle rollover accident during a routine training exercise - which later became the inspiration for COCOON Knee Flex Pro.


I underwent dozens of surgeries and didn't have full function in my legs. I was stiff everywhere, it hurt to move and I was forced to use assistive devices just to get up and go anywhere. Depression, anxiety, anger, frustration, and fear clouded my mind as I worried about a life filled with pain. Then, after months of therapy, pain killers, and dozens of other treatments that just didn’t work.

I finally said enough!

Instead of spending the rest of my days on pain killers and “managing” the pain, I decided I was going to learn everything I could about how to fix my body... and get back to who I was before the accident. 

Now I’ve Dedicated My Life To Helping Myself (And Others) Get Out Of Pain Naturally

I studied kinesiology at the University Of Illinois which taught me all about how the body works.


Next I got my doctorate in Physical Therapy from Northwestern University so I could learn how to fix it!


Today I’m a certified Doctor of Physical Therapy, licensed in the state of Illinois. 


And I’m a Certified Therapeutic Pain Specialist, as well as certified Strength and Conditioning Specialist.

I used what I learned in school about the human body and how pain works. Plus the commitment and dedication I learned during my time in the military and turn that into a career that helped me get myself out of pain. Now I dedicate my time to helping my patients do the same, so they can get back to living life on their own terms. I am proud to say that I succeeded...and COCOON was born. Today, Knee Flex Pro is still my customer favourite, it keeps you moving WITHOUT pain.


What I love about it is that it completely takes pressure off your knee, without requiring you to lay on the couch all day. That makes it easier for you to get up and start walking. Which means those important fluids can deliver the nutrients to your knee joints so they can actually heal over time. But the Knee Flex Pro is not just another joint sleeve or wrap for your leg.

The "Hot and Cold Control" Secret That Soothes Painful, Swollen, Aching Knees In Minutes.

It Keeps You Moving WITHOUT  Pain.

  • Microwave for 30 seconds for calming heat therapy to loosen-up stiff joints and boost blood flow for fast relief.

  • Freeze for 2 hours for soothing cool therapy to reduce swellings and recover faster so you can return to your day.

  • Revolutionary all-around hydropad provide stable knee protection while giving ultimate flexibility for full range of motion.

  • Ergonomic 360° design that gently compress, wraps around any knee and won’t slide off your leg. 

  • Full 90-Day No Hassle Returns

Knee Flex Pro™ Improves Blood Flow, Relieve Swelling, And Energize Tired, Achy Knees And Joints

  • You’ll notice a warm, massage like feeling while you’re walking or moving as the built in meniscus stimulators work their magic.

  • It gives you the options to microwave for calming heat therapy or freeze for soothing cold therapy to recover faster and sleep better so you can return to your favourite activities quicker.

  • And you’ll love how breathable the material is while being slim and discreet so it can easily be hidden under clothing.

How They Work

Knee Flex Pro™ are compression sleeves that use hot and cold control technology. With specialized 360° leak proof hydropad to wrap around and create pressure on the muscles in the legs, arms, knees and ankles, the pain relief is almost instant. ​

You can microwave the sleeve for 30 seconds for calming heat therapy, which loosen up stiff, achy joints and improves the blood circulation from the bottom of your knees up the top.


You can also freeze the sleeve for 2 hours for soothing cold therapy, which reduce swellings and combat inflammations so you can get back to your favourite sport faster.

If your legs or knees are even just a bit swollen, you owe it to yourself to try Knee Flex Pro.

In fact, they’re among the most popular pain relief tools I offer my clients…

I love that they’re natural and don’t require any pills to swallow or weird exercises that patients never like to do.

Instead, what you’ll get is immediate relief from tired, achy, stiff knees. 

And you’ll be able to maintain healthy blood circulation throughout your legs and knees, which helps take pressure off your hips, feet and back.

Let Me Ask You...

Can you imagine what it would feel like to live without pain?


How would it feel to be able to get up and down stairs without having to yank yourself up with the railing?


What it would be like to not hear the bone-on-bone grind of your knees everytime you bent down to pick something up…


And how life would look if you could be active, healthy and pain free like you were in your 20’s and 30’s...

Pain Free Movement Is Our Promise Of The Knee Flex Pro And Over 23,000 People Have Already Seen Life Changing Results

I started feeling pain in my knees in my early 40’s. I work construction and I rely on my body to support my family. I can’t afford to take a day off. I needed two knee sleeves that was ready to work as hard as I do, so I bought the most robust sleeves I could find. The Cocoon Knee Flex Pro has totally transformed my workday. I went from always needing a break to working circles around the young bucks on the crew.


Andrew - Syracuse, NY

My knees were so bad, that I could barely walk up and down the stairs. I looked into getting surgery on them, but I found out my insurance wouldn’t cover the cost, and my doctor warned me about the risks. I felt trapped and was desperate for a way out. My daughter saw this on a Facebook ad and bought a pair for me. After just one week, my knees have gained the strength to not only get me up and down the stairs, but also I’m walking with my girls again!


Mike - Saint Paul, MN

My old coworker’s knees were so bad he had to quit his passion of being a mechanic for 30+ years, and last I heard he works at the parts store up the road for almost minimum wage. He always told me I need to take better care of my knees. The day he quit I bought these sleeves. I’m so happy I started when I did because I don’t know what I’d do if I could no longer do what I love.


Doug - Villas, NJ

Very comfortable and fits really well. I like wearing mine when I jog and the difference it makes is really incredible and easy. A bonus thing is that others don’t even notice that I’m wearing this. Sleek design and lay flat to air dry!
