Black Widow Mania is happening now! Hammer is proud to introduce another exceptional ball to the legendary Black Widow line, the new Black Widow Mania. Each Widow has consistently complemented Hammer’s lineup and outperformed its predecessor. The coverstock makes this Widow unique and takes performance to the next level. We tested every cover we have, and the clear winner was the HK22-Cohesion Pearl cover; yes, the same cover found on last year’s top-selling Hammer Effect! Cohesion continues to elevate performance, and it’s noticeable in the way the Black Widow Mania creates length and a sharper breakpoint than even the Black Widow 2.0 Hybrid. The Black Widow Mania is the perfect choice as a go-to ball after the Black Widow 3.0 or to combat any medium condition. The Gas Mask core, HK22, Cohesion, and the Black Widow name – what more do you need?
