WHY THIS ONE

Four things that decide whether you keep it on

Most knee sleeves fail the same way: they slide down after ten minutes and people stop wearing them. Nearly everything below exists to solve that.

Spiral stays down both sides
Flexible metal spirals sit either side of the joint and bend with you. They add side support that a plain elastic tube has nothing to offer.
A silicone ring around the kneecap
A contoured gel ring with over a hundred raised nodes cups the patella instead of pressing flat across it — which is what stops the front of the knee feeling squashed.
Knitted at different densities
3D knit rather than cut-and-sewn elastic, so it grips at the top, gives at the back of the knee, and does not bunch up when you bend.
A ventilated back panel
Airflow where the leg sweats most. It sounds like a detail until you are an hour into a match deciding whether to take it off.

HOW TO USE IT

Three steps, and measure before you order

  1. 1

    Measure around the knee first

    Around the middle of the kneecap with the leg straight: S is 13.5 to 15.5 in, M is 15.5 to 17.5 in, L is 17.5 to 19.5 in, XL is 19.5 to 21.5 in. Guessing from clothing size does not work.

  2. 2

    Pull it up rather than roll it

    Hands inside the top, draw the sleeve up the leg, and settle the silicone ring so the kneecap sits inside it. Rolling it up stretches the top band out of shape.

  3. 3

    Check the top band

    Two fingers should slide under it. Tight enough to leave a deep mark is a size too small being worn, not a firmer fit.

If the silicone ring is not sitting around the kneecap when you stand up, the size is wrong rather than the position. Message us and we will help you check.

IN USE

Where it earns its place

Walking
Long distances, hills, and days where the knee usually complains by the end.
Training
Squats, lunges and running, for compression and a knee that feels held.
Hiking
Especially coming back down, which is when knees notice the load.
Daily use
Standing work, stairs, gardening — the ordinary things that add up.

Before you use it

  • This is a compression sleeve for a knee that is already well. It is not a hinged brace and it is not a substitute for one after an injury.
  • Do not wear it tight enough to mark the skin deeply, and take it off if the lower leg tingles, swells or goes cold.
  • Take it off after activity. It is not made to be slept in or worn all day.
  • Do not put it over broken skin, a rash or an open wound.
  • If the knee gives way, locks or swells after use, stop and see a healthcare professional. That is not something a sleeve fixes.

This is sports apparel, not a medical device. It does not treat knee injuries, arthritis or any diagnosed condition. A knee that swells, locks or gives way needs a healthcare professional rather than a sleeve.

BEFORE YOU ORDER

Questions people ask

Is this one sleeve or a pair?

One sleeve. The manufacturer packs and prices it individually, and the listing photos say so plainly. Order two if you want a pair — the multi-buy discount takes 10% off at two items anyway.

How do I choose the size?

Measure around the middle of your kneecap with the leg straight and match it to the chart: S 13.5–15.5 in, M 15.5–17.5 in, L 17.5–19.5 in, XL 19.5–21.5 in. If you land exactly on a boundary, size up — slightly loose still gets worn, too tight does not.

Will it slide down when I run?

That is what the knitted top band is for, and it works when the size is right. If it still slides, the sleeve is a size too big rather than worn out.

How is this different from the spring knee support you sell?

Very different jobs. That one is a hinged brace with coil springs at the side, built to add rebound as the knee bends. This is a fabric compression sleeve with side stays and a gel ring — lighter, thinner, and made to be worn for hours rather than for a specific task.

Can I wash it?

Hand wash cold and air dry. Hot water and a tumble dryer ruin both the knit and the silicone ring, which are the two parts you are paying for.

How does the multi-buy discount work?

It comes off on its own at checkout, with no code to type. Two items anywhere in your basket take 10% off, three take 15%, four take 20%. They do not have to be the same product.

When will it arrive?

Orders are dispatched within 1–2 business days and usually arrive within 7–12 business days after that; tracking is emailed as soon as the parcel leaves. If it is not for you, unused items can be returned within 30 days — email us first for the return address.
