Sound familiar?
Sore knees change through the day. Most knee braces don't.
Swollen in the morning, better by lunch
A fixed brace is too tight in the morning… and too loose by the afternoon.
A sleeve that keeps slipping
You spend all day hitching it back up.
Kalmflex is made for all three. A dial you adjust in seconds… and a non-slip grip that stays put.

Stairs without the dread, finally
I've tried a few knee sleeves and they all slipped. This one stays put all day and the dial is brilliant. I tighten it for my walk and loosen it at night.

Arthritis in my right knee. Real difference.
Three years of arthritis. I wasn't expecting much, but I can walk further before it bothers me. The size matched the guide.

I bought two
One for each knee with the deal. You can't see them under my pants, so I wear them all day. The pad on the kneecap is really comfy.

Great for bushwalks
Wore it on a 12 km bushwalk. My knee felt held without feeling locked. Recommend.

The dial changes everything
My knee's swollen in the morning, so I loosen it. Later on I tighten it again. No other sleeve lets you do that. One star off for the delivery time.

I wear it every day
Light, doesn't get hot and you can't see it under a long dress. My morning walks are a pleasure again.

Good quality
Well made, and the silicone grip really does its job. It doesn't slip, even when I'm out in the garden.

FAQ
Questions?
Can't find your answer? Email us at info@kalmflex.com
How do I choose my size?
Go by your weight: M (up to 75 kg), L (76–90 kg), XL (91–109 kg) or 2XL (110 kg and over). Between two sizes? Take the bigger one. Size exchanges are free.
Can I adjust how tight it is?
Yes. Tighten it for stairs and long walks… loosen it when your knee is swollen. It takes a few seconds.
How long can I wear it?
All day. Take it off at night. If you feel numbness or tingling, loosen it a little.
Will it help if my knee is “bone on bone”?
Many people in that situation wear it to feel steadier on their feet. It doesn't repair cartilage… but support that steadies the knee can make stairs and walks more comfortable. If in doubt, have a chat with your GP or physio.
When will I feel the difference?
Most people feel the extra support from the first few steps. Wear it every day for a few days to find your ideal setting.
What if it's not right for me?
You're covered by our 90-day money-back guarantee, from the day your order arrives. Email us at info@kalmflex.com and we'll walk you through it.
How long does delivery take?
Orders ship within 1–3 business days. You'll get a tracking number by email.
Which product should I choose?
Start where it hurts. For knees, most people choose the Kalmflex Knee Sleeve.
How do I wash it?
Hand wash in cold water, then let it air dry. No dryer: heat ruins the stretch.
