Z-Fit™ Slim Flex Adjustable Weighted Vests

Elevate your training with the Z-Fit™ Slim Flex Collection. Designed with a sleek, zip-up athletic profile, these weighted vests offer a body-contouring slim fit that moves with you, not against you.

Each vest features dedicated pockets for our removable Z-Fit™ weight blocks—crafted from a smooth, uniform blend of flexible silicone and fine iron sand to eliminate heavy, awkward hard spots. Customize your load in seconds, then fine-tune your tightness using the adjustable side straps for total stability and zero bounce. Whether you're running, doing high-intensity cardio, or powering through daily conditioning, the Z-Fit™ Slim Flex delivers maximum resistance with seamless comfort.
