Overview
At about 0.09 kilograms and finished in bright yellow, the SKLZ 3508 is a single reaction ball meant to bounce unpredictably during reflex training drills.
At roughly 3 ounces, this reaction ball is light enough to toss repeatedly during a drill session without fatigue, and the bright yellow color keeps it visible when bounced across a field or gym floor. SKLZ sells a range of reflex and agility training tools, and this listing covers a single ball rather than a multi pack.

Who it's for
Athletes and coaches running solo or partnered reflex drills who want one ball rather than a set. Not built for general strength or cardio training.

- Light at about 3 ounces for repeated use

Performance notes
The ball's multiple flat faces send it off at random angles on each bounce, which is what forces a quick, unpredictable reaction from the user during drills.
