Knee sleeves are a type of fitness equipment designed to protect and support the knees during exercise. They are usually made of neoprene or a similar material and are worn over the knee joint.

Knee sleeves have several advantages, including:

1. Increased stability: Knee sleeves help to stabilize the knee joint, reducing the risk of injury during exercise.
2. Improved circulation: The compression provided by knee sleeves can help to improve circulation, reducing the risk of swelling and inflammation.
3. Pain reduction: Knee sleeves can help to reduce pain in the knee joint, particularly for those with conditions such as arthritis or patellar tendonitis.
4. Increased performance: By providing support and protection to the knee joint, knee sleeves can help to improve overall performance during exercise.

Overall, knee sleeves are an excellent investment for anyone who wants to protect their knees during exercise and improve their overall fitness performance.
