Three kinds of knee pain, and how Cocoon fixes each one.
What is happening inside the joint, and exactly what the sleeve does about it.
Morning stiffness
Overnight the joint cools, the fluid inside it thickens and the muscles around the knee tighten. That is why the first ten minutes of the day feel like rust.
How Cocoon helps
- Warm it while the kettle boils.Two minutes in the microwave, then pull it on before you stand up.
- Heat loosens, gel holds it there.Warmth relaxes the muscles and brings blood flow back to the joint. The 360 gel keeps that warmth on the whole knee, not one spot.
- Get up loose, not stiff.Ten minutes later the joint moves freely, and the compression keeps it supported on the stairs.
Workout recovery
Squats, lunges, stairs. Every session leaves micro-swelling in the joint that stiffens as it cools. That is what you feel the next morning.
How Cocoon helps
- Straight from the freezer.On for 15 to 20 minutes while you shower or cook dinner.
- Cold stops the swelling settling in.It slows nerve activity to dull the ache and brings swelling down, while compression limits fluid building up around the joint.
- No ice, no drips, no straps.It stays put, so you keep moving while it works.
Running and marathon training
Every stride loads the knee with several times your body weight. Soreness peaks 24 to 48 hours after a long run, right when the next one is due.
How Cocoon helps
- Cold as soon as you are back.15 to 20 minutes to take the heat out of the joint and cut the swelling.
- Warm before the next run.A few minutes of heat the next morning so the joint and muscles are loose for the first mile.
- Built for the routine.The grip lining holds on a cool-down walk, and it packs flat in the carry bag for race day.

Choose your setOne sleeve. Two therapies.
Freeze it for swelling and sharp pain. Warm it for stiffness and dull aches. Same sleeve, same fit.
Cold for swelling
For new injuries and flare-ups: sharp pain, a swollen knee, soreness from overuse. Cold slows nerve activity, which dulls pain, and brings swelling down.
- Keep it in the freezer between uses so it is ready when you are.
- Slide it on right after exercise for 15 to 20 minutes.
- Wear it before bed to settle an aching knee.
Heat for stiffness
For long-running pain: dull aches, stiff joints and tight muscles. Heat loosens the muscles around the knee and improves circulation.
- Warm it in the microwave in short bursts until it is comfortably warm, never hot.
- Wear it first thing in the morning to ease stiff joints.
- Keep it on while you rest. The gel is lavender-infused.
