The Physiologix Essential Thigh Support is designed to provide light support and maximum comfort without restricting movement. It features an enhanced, lightweight, breathable, and durable stabilizer that helps prevent re-injury. The ergonomic design provides uniform support and compression, while the 360° stretch and contour design prevent slippage and ensure a proper fit. The re-enforced edges add to the product's durability. To find your size, measure around the centre of your thigh. The available sizes are: Small (21-23 inches/53-58 cm), Medium (23-25 inches/58-64 cm), and Large (25-27 inches/64-69 cm).
