Original Pump Cover

This oversized pump cover from Sonder is engineered with heavy-duty, moisture-wicking fabric that traps body heat to keep your muscles warm and pliable between sets. Its structured, boxy fit allows for a full range of motion while minimizing airflow, creating a localized thermal environment that enhances blood flow and vascularity. By keeping your core and extremities primed, it ensures you reach maximum muscle engorgement faster and maintain that peak pump throughout your entire workout.
