Dynamic spring-loaded resistance: Replaces static weight with 12 removable ProPulse® cartridges that activate with your natural movement.

A compact, everyday-wear design that delivers an effective training stimulus without the bulk of a traditional weighted vest.

Designed for movement and performance: Loads the body during the lowering phase and recoils during the launch phase to support greater power, explosiveness, and reduced ground-contact time.

Versatile and joint-friendly: Use it for walking, light exercise, strength training, running, jumping, footwork drills, and plyometric training.
