ZELUS Weighted Baseball Set with Seams for Hitting and Pitching

In this review of the ZELUS weighted baseball set, the verdict is straightforward: athletes who want a progressive, real-feel training tool will find a lot to like. The six-piece set covers a wide weight range from 3.5 oz to 35 oz and the balls have raised seams that mimic a real baseball, so hitters and pitchers can practice mechanics without losing feel. The set is built for repeated use with PVC construction, iron sand filling for resistance, and a 420D Oxford carry bag that keeps everything together for practices or travel.

Key Features

• Six weights included: The set contains 3.5 oz, 8 oz, 12 oz, 16 oz, 21 oz and 35 oz balls to progress strength and control systematically.
• Real-feel raised seams: Raised seams provide a textured grip and a realistic surface that helps transfer training to on-field performance.
• Iron sand filling: High-quality iron sand adds resistance for improved swing power and more stable throwing motion during drills.
• Durable PVC construction: The PVC material stands up to frequent use and retains shape for long-term training sessions.
• Adjustable air nozzle: A convenient air valve lets users fine-tune weight feel and hardness to match specific drill needs.
• Portable carry bag: The included 420D Oxford fabric bag makes it easy to transport the set to practices, cages, or travel.

Who It's For

The ZELUS weighted baseball set is best for youth and adult players who want to add targeted plyometric and strength work into batting and throwing routines, including off-season programs and skill development sessions. Coaches running small-group drills will appreciate having multiple weights to match different athletes and drill goals.

Players who need a regulation leather practice ball for live games should look elsewhere, since these PVC, iron sand-filled balls are purpose-built for training and not game play. Those seeking a minimal single-weight ball for casual backyard play may also find the full six-piece set more than required.

Pros & Cons

Pros

• Carry bag keeps the set organized and portable for practices or travel.

Cons

• Not intended as regulation game balls, so they are for training use only.
• Heavier weights may require supervision for younger athletes to avoid improper mechanics.
