Silipull Javelin Throwing Ball 800 g — Notched Rubber Training Ball with Ribbed Grip

Silipull Javelin Throwing Ball is an 800-gram, single-piece rubber notched training ball designed to replicate the javelin carry and show release quality during off-season drills.

This notched javelin ball from Silipull is made from a single cast rubber shell with a molded finger notch to simulate the javelin grip, offering a durable, weather-ready training tool for throwers and coaches. Shipped each in its own box with a foam collar, the ball arrives protected and ready for immediate use on turf, track, gravel or indoor bays. Its ribbed rubber skin improves grip during sweaty practice sessions, and the 800 g weight matches the standard meet weight used by adult men so athletes can maintain proper arm path and release mechanics year-round.

How does the notch recreate a javelin carry and release?

The molded notch fits between two fingers while the rest of the ball sits in the palm, imitating the feel of a javelin tail and leading edge. Because the tail leads in flight and the ball lands nose-first, coaches and athletes can instantly see whether an athlete’s release was clean and on-angle.

• Molded notch between fingers mirrors real javelin grip
• Tail-leading flight shows release quality at a glance
• Palm seating encourages correct wrist and forearm position
• Immediate visual feedback for coaching corrections

What makes the rubber shell suitable for repeated practice and varied surfaces?

The Silipull ball is cast from a single, solid rubber compound with a ribbed exterior that resists splitting or deformation from frequent landings. There’s no metal tip or multi-part construction to bend or detach, so the ball stays round and dependable after hundreds of throws on turf, track, gravel or indoor mats.

• One-piece rubber prevents splitting and component failure
• Ribbed texture enhances grip in wet or sweaty conditions
• Durable under repeated impacts on multiple surfaces
• Low maintenance—no tips or screws to adjust

Why choose the 800-gram weight for training?

The 800 g weight corresponds to the official men’s competition weight, so practicing with this ball preserves realistic arm path and release timing. Using the same mass athletes throw in meets helps keep muscle memory and technical cues accurate during off-season conditioning and indoor drills.

• Matches adult men's meet weight for consistent mechanics
• Helps maintain arm path, timing, and release feel
• Enables realistic indoor or off-season practice sessions
• Portable enough for gym bays and field-side drills

How is the Silipull Javelin Ball packaged and stored?

Each ball ships individually boxed with a snug foam collar to prevent scuffs and preserve the rubber skin. The box doubles as off-season storage in a kit bag or team trunk, keeping the ball protected between training cycles.

• Single-packed in box with foam collar to avoid marks
• Box suitable for compact, labeled storage in bags or lockers
• Ready-to-use on arrival—no assembly needed
• Ideal for gifts, team equipment, or personal training kits

Who is this for: The Silipull 800 g Javelin Throwing Ball is made for track & field throwers, strength and conditioning coaches, high school and college athletes, and anyone running off-season or indoor javelin drills. It’s also a practical gift for throwers who want to maintain technique when a full javelin session isn’t possible, and for coaches seeking a durable, low-maintenance tool for group practice and feedback.
