Z-Fit™ Weight Vests

Forget everything you know about bulky plates and rigid sandbags. Our proprietary Z-Fit™ technology infuses fine iron powder into high-grade silicone, creating a seamless, one-piece weighted layer. It doesn’t just sit on you—it breathes with you. Experience a vest that mimics your body’s natural mechanics, providing constant tension without the friction.

Built for hot-weather training, the breathable outer fabric stays cool and dry against your skin—so summer runs and outdoor workouts never feel like a battle against your gear.

Is the fabric breathable enough for summer training?

Yes — the outer fabric is designed to feel cool against your skin and stay breathable, even during high-intensity sessions in the heat. No more stopping mid-run because your gear feels like a sauna.

How do I choose the right weight?

For everyday training or walking, 5–10 lb is a great starting point. If you're building strength or doing more intense workouts, 15 lb and up will give you a better challenge. Not sure? Read More:What Size Weighted Vest Should I Get

What's the difference between the X-Shaped, Y-Shaped, and Flex vests?
  • X-Shaped: Fixed weight, sleek and low-profile — great for running and everyday wear.
  • Y-Shaped: Adjustable weight (8–32 lb) for those who want to scale up over time.
  • Flex: Full-coverage fit available in 10 lb or 15 lb, built for strength and conditioning work.
How do I clean my Z-Fit™ weighted vest?

Care varies slightly by style:

  • X-Shaped & Flex Vests: Wipe down with a damp cloth or disinfectant spray after each use. For a deeper clean, hand-wash by soaking occasionally — machine washing is not recommended.
  • Y-Shaped Vest: Simply remove the weight pouches and toss the outer vest in the washing machine.
Will the vest slip or bounce during high-impact workouts?

No — the snug, body-hugging fit and adjustable straps keep the vest secure whether you're running, jumping, or lifting.

Can I wear it under or over my workout clothes?

Either works. Most people wear it directly over a fitted top for the best contact and stability, but it's comfortable enough to layer over light clothing too.
