Picked up bowls this year and my knee started complaining after every game. These let me keep playing without the ache afterward.
The pair I had before squeezed so hard I had marks for hours. Two days in these and I can actually feel my leg again by the end of the day. Completely different feel.
Used these during physiotherapy after a minor knee procedure. My physiotherapist said the compression level was exactly what she'd recommend.
Every compression sleeve I've bought eventually bunches up behind my knee by midday. These stay put even during a full workday on my feet.
I live somewhere hot and every other sleeve I tried made my knee sweat under the fabric. The bamboo material actually stays comfortable even in summer.
I've tried three other brands and these are the only ones I actually look forward to putting on. The bamboo fabric doesn't get sweaty like the neoprene ones I had before. Wearing them daily now.
Got these for my mother who has arthritis in both knees. She wears them around the house constantly now and says it's the first thing that's actually helped.
I've tried three other brands and these are the only ones I actually look forward to putting on. The bamboo fabric doesn't get sweaty like the neoprene ones I had before. Wearing them daily now.
I teach yoga and kneel a lot during classes. These give just enough cushion and support that I'm not dreading floor poses anymore.
Had to stop running because of knee pain. Eased back in wearing these for support and I'm up to 3 miles again with no flare-ups.
Not too tight, not too loose. Enough support to keep my knee feeling stable all day, even after a long walk. Buying two more pairs for my husband.
He has a couple other brands and didn't think these would be different. After one day he came and told me they weren't even close. Thank you.

Wore these on a 10 hour flight to keep the swelling down and it actually worked. Ankles and knees felt normal when I landed instead of puffy.

I live in a third floor walk-up and stairs were becoming a real problem. A week into wearing these during the day and going up is noticeably easier.
I'm on my feet all day as a hairstylist and my knees used to be throbbing by hour eight. Three weeks in these and I get home and barely notice them. Ordering a second pair for backup.

Works fine for sitting around the house or short walks, but I wouldn't rely on it for anything more active than that.

I wear these almost daily so I ordered a second pair. Wash easily and dry fast, haven't lost their stretch after weeks of regular washing.

My doctor suggested a basic compression sleeve from the pharmacy. I tried these instead based on reviews and they're noticeably more comfortable and supportive.
I needed something I could wear to work under slacks without it showing. These are thin enough that nobody notices but still give real support.

Product itself is great quality, support is noticeable within days. Just took longer to arrive than the estimate said.

The grey is more of a light heather than what showed in the photos, but the actual knee support and comfort are great so not a big deal.
Ordered based on the size chart but it's noticeably tight behind the knee when I bend, makes it uncomfortable after sitting a while.

The FLEX+ Bamboo Knee Sleeve guide
The FLEX+ Bamboo Knee Sleeve is a soft, breathable knee compression sleeve made for people who want steady support without the heat, sweat and itch of a neoprene brace. It wraps the whole joint in gentle, even compression, so your knee feels supported on walks, stairs, gardening, pickleball and long days on your feet. If you have been searching for a bamboo knee sleeve you can actually keep on from morning to night, this is the one our customers reorder most. Browse the full knee sleeves collection to compare styles.
Most knee braces are made of thick neoprene. It traps heat, slips as you move and can leave red marks after an hour. Copper-infused sleeves usually use the same synthetic knit with a small amount of copper thread. Our sleeve is knit from viscose from bamboo blended with nylon and spandex, which gives it three things people notice right away:
We designed it for adults who live with everyday knee discomfort and want something simple that does not get in the way. Many customers tell us it is the best bamboo knee sleeve for arthritis they have tried, mostly because it is comfortable enough to keep on. Customers wear it for:
A knee sleeve is a comfort and support product, not a treatment. If you have sudden swelling, a recent injury or pain that does not improve, talk to your doctor or physiotherapist first.
Gentle, even compression around the joint gives your knee a supported, held-together feeling and improves body awareness (proprioception), which many people find makes movement feel steadier. Light compression can also help limit the puffy feeling around the knee after a long day. The FLEX+ sleeve uses gentle to moderate compression that is firm enough to feel, but comfortable enough for all-day wear. It is not a medical-grade compression garment.
| Feature | Details |
|---|---|
| Material | Viscose from bamboo, nylon and spandex (see product label) |
| Compression | Gentle to moderate, even around the joint |
| Fit | Slim, anatomical knit that stays in place under clothes |
| Sizes | S to 4XL, including plus sizes |
| Colours | Grey, Black, Navy, Red, Cream and Pink |

| Care | Hand wash or machine wash cold in a laundry bag, air dry |
Use a soft measuring tape around the centre of your knee cap with your leg slightly bent, then compare it with the size chart on this page. If you are between two sizes, choose the larger size for comfort. A knee compression sleeve should feel snug, never painful, numb or tingly. Need help? Our FAQ page covers sizing, shipping and returns, and every order is backed by our 30-day comfort guarantee.
Finding a knee sleeve that fits a larger thigh and calf without rolling down or cutting in is hard, which is why FLEX+ runs from S all the way to 4XL. The plus sizes use the same slim bamboo knit, just with more stretch and a wider top band, so the sleeve stays put without a tight ring above the knee. Measure around the centre of your knee cap and pick your size from the chart; when in doubt, size up.
Many customers combine the knee sleeve with the FLEX+ Bamboo Calf Sleeve for tired legs, the FLEX+ Full Leg Sleeve for thigh-to-ankle coverage, or EASE+ Bamboo Compression Socks for swollen feet and ankles.

Is a knee sleeve good for arthritis?
Many people with knee osteoarthritis find that a soft compression sleeve makes daily movement feel more comfortable and supported. It does not cure arthritis, but it is an easy, drug-free comfort option to discuss with your doctor.
Can I wear a bamboo knee sleeve for sleeping?
Some customers do, especially in winter, because the gentle warmth and compression help their knee feel less stiff in the morning. If you want to sleep in it, wear your true size (never a smaller one), make sure it is not folded behind the knee, and take it off if you notice numbness or tingling. If you have circulation problems or diabetes, ask your doctor before sleeping in any compression garment.
Bamboo knee sleeve or bamboo knee brace: which do I need?
A sleeve gives gentle compression and warmth for everyday aches and is slim enough to wear under trousers. A hinged or strapped knee brace is designed for instability or injuries. If your knee gives way or you have a recent injury, ask a clinician which option is right for you.
Can I wear it all day?
Yes. The breathable bamboo knit is made for all-day wear. Remove it if you notice numbness, tingling or skin irritation.
Do you make a bamboo compression knee sleeve for men and women?
Yes. FLEX+ is unisex and sized by the measurement around your knee, not by gender, so the same size chart works for everyone.
