This open-patella breathable knee sleeve is designed for sports support and everyday knee protection. Made with elastic, body-fitting fabric and a contoured compression structure, it helps provide stable support and comfortable compression around the knee joint. The open patella design helps relieve pressure on the kneecap during movement, while the padded circular support ring enhances surrounding stability and overall fit. A breathable mesh panel on the back improves airflow and helps reduce heat buildup, making the sleeve more comfortable for extended wear. Lightweight, flexible, and easy to wear, it is suitable for running, fitness training, basketball, badminton, cycling, and daily knee care, offering a practical balance of support, comfort, and breathability.
