Envy

Be the envy of the lanes with Envy from Hammer Bowling.

This new line from Hammer features all-new bowling technology to provide the latest and greatest in bowling performance. Featuring the new Launcher Asymmetric core, you can anticipate an aggressive midlane read with a devastatingly strong backend reaction. 

Wrapped in the Envy solid reactive coverstock, finished at 500/1500 Siaair Micro Pad, will truck right though heavy oil conditions to provide max hook downlane.
Here's what Hammer has to say about Envy:

The non-Hammer fans will have ball envy when they see this new Hammer ball out-hook and out-strike their balls. The new Hammer Envy was designed to be the strongest Hammer ball ever created. We started with the new asymmetric "Launcher" core that is packed with impressive features. The Launcher core has both a flip block and our exclusive radial disc technology; these components move mass away from the center, creating an increased imbalance for a stronger reaction throughout the lane. For the cover, we went with the ultra-aggressive Envy Solid cover, found initially on the Obsession and ensuring plenty of hook in oil. Don't have ball envy… Add the new Hammer Envy to your arsenal.
