Great non-neoprene knee support sleeve
I’m on my 4th one of these knee sleeves.They are a woven stretchy fabric, that moves with you and breathes. I’ve used neoprene and “copper” knee sleeves and these are much preferred. I don’t smell of rubber, nor are they excruciatingly tight, like the other two I mentioned. Pay attention to the sizing and if you’re on the larger side of the size, purchase the larger sleeve – that’s a mistake I made and they wouldn’t accept an exchange. Ah well, it will go to a friend. I’ll continue to buy these as I need them. They help to keep my knees stable while exercising.

Good Product
it is perfect would fit for M/L size. Moving activity is a little slip but it is ok

Fit
Although I measured my knee as mentioned in the product’s marketing material, the knee sleeve I ordered was way too small. The top rolled down upon itself, cutting off blood flow to my leg. Looks like it might help if it fit correctly.

Great breathable compression sleeve.
I have had knee issues for a few years now. I used a brace with side supports for a couple of years (meniscus issue) and finally healed to where the side braces were causing problems it seemed. I decided to go to compression support only. These supports are substantial, comfortable, and breathable. I must wear these for sometimes 16 hours at a time and they are comfortable enough to do so plus add a good amount of support. After trying 4 different kinds, these are by far the best for me.

Provides support when you need it.
If you are close to the max measurement in a size, order a size up or it will be too tight and cut off circulation. Otherwise, a good support device for the knee when you are rehabbing or need a bit of extra support. Good quality product from a company that knows what they are doing.

1″ longer, a bit less tight than Mueller’s original but stays in place
The Mueller Thermo Reactive knee sleeve was a replacement for a different brand of sleeve that I used indoors for my “bad” knee when it was tender and slightly swollen. The Thermo Reactive sleeve is 1” inch longer than Mueller’s regular, black and white 4-way stretch knee sleeves that I wear outside the house. Despite being a bit less snug than the regular sleeves, the Thermo Reactive sleeve stays put and is comfortable with excellent support. Knee sleeves need to fit closely to feel secure; if you do not feel surefooted immediately after putting them on, try another brand that fits you better. Fortunately, Mueller’s S/M size is perfect for my knees, and this new model is a great help to me.

Comfortable and Supportive
Love the product. Just bought another set. I’m in the middle of the Small sizing, and it fits very well. Also I washed the sleeves on a delicate setting, hung them to dry, and they were ready to go the next morning.
Cliente Amazon –
El producto es de calidad y muy útil, al igual que lo veo en otros comentarios, coincido en que sí se va resbalando un poco, sobre todo si se camina bastante con ella puesta, y se tiene que estar subiendo y reacomodando ocasionalmente. Me ha dado buen resultado si estoy solo sentada o de pie, como en la cocina mientras preparo algo, también me ha servido bastante ya que empieza a molestar la rodilla de tanto subir y bajar las escaleras.
