Breathable and SweatAbsorbing Comfortable Fabric The rear ventilation hole wicks away sweat, while the soft, breathable fabric absorbs moisture, keeping the skin dry and ensuring a comfortable fit. It stays securely in place without slipping and offers elasticity to effectively reduce impact on the knees during exercise. 3. Adjustable Knee Stabilizer The knee sleeves have an adjustable Velcro strap for a comfortable fit, making them easy to put on and wear. Elastic cuffs prevent the knee sleeves from rolling or sliding during workouts. 4. Ergonomic Design The knee braces are designed according to the structure and movement characteristics of the human knee joint, making them suitable for individuals with levels of knee activity. They effectively cushion and distribute pressure in all directions, keeping the knees warm and lubricating the joints for sports protection and pain relief.
