Why Flex Works

The Flex Knee Sleeve uses graduated compression technology — snug at the joint, slightly looser above and below — to support natural blood flow while gently stabilizing the knee.
This reduces inflammation, improves joint alignment, and relieves pressure on your ligaments and cartilage.
 

🔹 Side Stability Panels: Prevent unwanted twisting and buckling.
🔹 Kneecap Cushion: Protects soft tissue and eases patellar tracking.
🔹 Breathable, Moisture-Wicking Fabric: Wear it all day without discomfort.
🔹 Low Profile Design: Fits easily under jeans, leggings, or athletic wear.
