How Primara helps your knee feel supported
Built to give you secure, adjustable support through training, walking, work, the stairs, and everyday movement.
Helps reduce slipping
Most supports slide down the moment you stand. Primara is shaped to your leg with a silicone grip lining, so it holds in place and stays put.
Helps you feel more stable
A spring stabiliser runs down each side of the knee, backing it against twisting and giving way, so you feel held through every step.
Helps you adjust support instantly
Your knee does not feel the same every day. Turn the dial on the outer side to set it firmer or lighter, any time, without taking the brace off.
Helps support without the bulk
No rigid hinges digging in. Primara's 3D compression knit is light, breathable, and sits low under clothing, so support moves with you all day.
Primara is built for support you can actually trust. Secure when you move, adjustable when you need it, and comfortable enough for daily wear. That is why it was rated the #1 knee support of 2026.

Don't wait until your knee forces you to stop.
You already feel it. The knee that aches after a long day, gives way without warning, or makes the stairs and the dog walk harder than they used to be.
Most people do not look for knee support when everything feels fine. They look when the knee feels less stable, less trusted, and less comfortable than it used to be.
Primara was built for that moment. Secure support, tension you set yourself, and a fit that stays in place.
1You keep pushing through it
It is easy to brush off a bad knee when you are busy, working, or trying to stay active. But pushing through it without real support can make every step feel less certain over time.
2You start changing how you move
When your knee does not feel stable, your body starts to compensate. Shorter steps, avoiding the stairs, skipping the things you enjoy, or leaning on your other leg.
3Confidence starts dropping
It is not just the discomfort. It is the hesitation before you move. The step down. The stairs. The long day on your feet.
4Basic movement feels like a gamble
When support feels inconsistent, everyday movement starts to feel unpredictable. Primara helps you feel secure, supported, and ready to move with confidence again.

Clinician-informed support
Built around what knee specialists look for.
Primara Active Knee Support is designed around the core things physios and sports clinicians look for in a knee support: stability, adjustability, comfort, and a fit that stays in place.
“
Good knee support should feel secure without restricting normal movement. The biggest issue with standard sleeves is that they slip, bunch, or apply pressure in the wrong places. Adjustable support gives people more control over how the brace feels through the day.

Support is only useful if people can actually wear it. If it slips, digs in, or restricts movement too much, they stop trusting it.

FAQ
Questions before you choose Primara?
Straight answers about fit, support, comfort, and how the dial system works.
Most sleeves give you one fixed level of support, decided before you even put them on. Primara has a tightening dial, so you set the support yourself, and change it any time your knee feels different.
Turn the dial on the outer side of the knee to bring the support in snug. Firmer on a heavy day, lighter on a good one. You can adjust it on the move, no need to take it off.
Silicone anti-slip dots grip the inside of the knit, and the shape is contoured to your leg rather than a straight tube. Together, that is what keeps it in place through movement.
No. Double-sided spring stabilisers sit flat down each side of the knee for stability against twisting and give-way, without the bulk or dig-in of a hinged brace. Low-profile enough to wear under clothing.
Yes. Primara is sold as separate left and right units, with the dial always sitting on the outer side of the knee. Order for the side that needs support, though most customers find getting a pair the better option, since it means both knees are covered and you are never caught without support on your other side.
Measure your thigh 6in / 15cm above the centre of your kneecap, then match it to our size guide. If you land between two sizes, choose the larger size and tighten with the dial.
You set the tension yourself with the dial, and you can loosen it any time. No tourniquet feeling, no guessing.
Yes. The 3D compression knit is light and breathable, so it stays comfortable through a full shift, a full day, or a full session.
No. Primara is worn by people recovering from injury, people managing arthritis or everyday wear, and athletes training through old injuries. The dial lets everyone set the support that is right for them.
A cheap sleeve gives you one fixed tightness, decided before you put it on, and most stretch out or slip within weeks. The dial is hardware no cheap sleeve has, so you keep control and keep the fit, wear after wear.
Primara is built with a 3D compression knit and spring stabilisers designed to hold their shape through regular daily wear. You are also covered by our 30-day money-back guarantee.
You are covered by a 30-day, no-questions money-back guarantee. Try it, and if it is not right for you, send it back.
Yes. Hand wash in warm water, being gentle with the dial and stabilisers, then lay flat to dry. Avoid the tumble dryer, as heat can affect the dial and stabilisers.
No. Primara is designed to support your knee day to day, but it is not a substitute for medical advice. If you have a medical condition, speak with a healthcare professional.

“I finally felt like I could trust my knee again.”
★★★★★After trying sleeves that slipped or bunched, this felt completely different. It stayed in place, felt secure, and gave me confidence moving around again.
Mark P. Verified Buyer
Everyday / Active
“I stopped constantly pulling my support back up.”
★★★★★I wanted something I could wear through the day without constantly adjusting it. Primara is comfortable, adjustable, and I barely notice it until I'm grateful it's there.
Linda S. Verified Buyer
Training / Gym
“It stayed locked in through the entire session.”
★★★★★Most sleeves start moving once I'm sweating. The dial and fit gave me control, and it stayed right where I needed it while I trained.

Customers say
AI Summary
Across reviews, customers most often say the support stays exactly where they put it, with very few mentions of the slipping, rolling or bunching they describe with cheaper sleeves. The dial comes up again and again, especially being able to tighten it before activity and ease it off afterwards. Several reviewers compare it favourably to bulkier hinged braces, saying it feels far less restrictive while still giving real side support. Comfort and all-day wearability are mentioned frequently too, particularly by people on their feet for long shifts, alongside praise for how well it holds its grip and shape with regular washing and daily use.
