Knee circumference 38cm, L-size: It feels tight when first worn, but after wearing, there is a slight compression which seems to be good for recovery. After freezing for 20 hours, it maintains a cooling sensation for about 5-10 minutes when worn. Wearing for 15-20 minutes and then taking it off greatly helps in recovering knee and surrounding muscle fatigue. Highly recommended.

Size? Well, I'm trying to buy it for the knees haha. The largest size being sold is L, so I bought it thinking it's for the calves. I haven't measured it yet haha. I recommend trying it on before buying.
C
not only does this feel comforting to my damaged knee, it fits well enough that i can walk about in it, and the first time i put it on I actually thought, that's not just soothing its actively pleasant.
only downside is how fast they cool down, maximum an hour, hence buying more so I always have one on hand.
Thank you so much for your review Cherry! We're so glad our knee sleeves are providing you with pain relief 😊
S
I have fibromyalgia and being able to swap between hot and cold is brilliant. Both the hot and cold provide so much relief. I really recommend these items!
Thank you so much for your feedback Sam! We're so delighted to hear this 🙂
J
My son really loves this product for his knee after training. Much better than ice packs in sleeves. Highly recommended.
We're so happy to hear this Jill 🙂 thank you so much for your feedback!
W
I made a good purchase. I'll use it well.
R
It's really practical. Size might be a bit small.
A
This ice/heat sleeve id so great as i've done my recovery and rehab with s broken arm and wrists. Im using it both ways when my arm swells i ice it and when im about to do rehab i can warm it up quickly in the microwave.
I would recommend this sleeve to anyone recovering from a bad injury. I may even get another keep one for heating up and one in the freezer.
C
I recommend it. It's a bit small, but comfortable and nice.
P
Very good product. Very practical.
R
It's a good product~~^^
M
It fits perfectly on the calf.
C
It's like the sleeve of a neoprene, it fits snugly.
S
Much heavier than expected, but soft & easy to slip on, with plenty of stretch to fit most legs! Only tried the "cold" so far, but SO much easier & better than a bag of peas! Really helps my arthritis. Well worth the money! Would recommend
T
It's cool and nice. I'm 179 cm tall and weigh 70 kg, but when I put it on my knees, it slightly bulges on the side.
G
Just like the previous one, this is what is being sought in this case for the arms.
A
After using it, I can say it's spectacular. The only thing I would recommend is a sports-style sleeve to put between the skin and this cold sleeve. Despite this, it's what I was looking for.
M
It's a bit tight, but the cooling effect is definitely noticeable. Very good.
T
Good product, size M fits well for a 38cm calf.
G
It's good for knee icing, but the cooling feeling diminishes after about 15 minutes.
Still effective
C
Item as described
