Core Design: Inner Power of Pure Envy

At the heart of the Hammer Pure Envy is its Launcher Core . This core is designed to rev up quickly and create a strong, continuous motion on the back end. With a low RG of 2.505 and a high differential of 0.053 , the ball generates significant flare, creating a reliable roll and angular motion that’s perfect for medium to heavy oil conditions. The additional Mass Bias Differential of 0.021 adds to the angularity, ensuring powerful, sharp transitions and consistent hitting power through the pins.


This core is ideal for bowlers seeking strong backend finishes and better control in challenging oil conditions.

Coverstock: HK22 - Cohesion Hybrid

One of the most exciting aspects of the Pure Envy is its innovative HK22 - Cohesion Hybrid Reactive coverstock . The HK22 coverstock is Hammer's latest development, known for its ability to create cleaner, more defined motion through the mid-lane while retaining a powerful backend reaction. The hybrid formulation balances both traction in oil and versatility, making it suitable for various lane conditions.


Out of the box, the Hammer Pure Envy is finished with a 500, 2000 Siaair finish, giving it the surface roughness needed to dig into medium to heavy oil patterns. This finish ensures early traction while still allowing for a smooth transition and aggressive backend motion.


The combination of the Launcher Core and HK22 coverstock creates a ball that can read the lanes well without sacrificing hitting power, making it a versatile choice for bowlers looking to control both the mid-lane and the backend.

On medium to heavy oil conditions, the Hammer Pure Envy delivers excellent performance. Thanks to its aggressive coverstock and strong core, the ball hooks early, gripping the lane with precision in the mid-lane. As the ball exits the oil, the core kicks in, producing a continuous, angular motion that finishes strong through the pins.


Bowlers who prefer playing inside lines or need a ball that can cut through heavier oil will appreciate the ball’s consistent ability to bite early and maintain energy. The combination of low RG, high differential, and mass bias differential ensures a dynamic yet controllable hook.


However, on lighter oil patterns, the Pure Envy may hook too early and become hard to control. It’s best suited for medium to heavy oil where its aggressive nature can shine without overreacting.

What type of lane conditions is the Hammer Pure Envy best suited for?

The Hammer Pure Envy is designed for medium to heavy oil lane conditions. Its HK22 - Cohesion Hybrid coverstock and 500, 2000 Siaair finish allow it to dig into the oil, providing excellent mid-lane traction and a strong backend finish. For lighter oil conditions, this ball may be too aggressive and could over-hook, making it less ideal for dry lanes.

How does the Hammer Pure Envy compare to other Hammer bowling balls?

The Hammer Pure Envy stands out due to its combination of the Launcher Core and the new HK22 - Cohesion Hybrid Reactive coverstock . Compared to other Hammer balls, it offers a more aggressive hook and earlier mid-lane traction, especially in heavier oil conditions. The Mass Bias Differential (0.021) also helps the ball create a sharper angular motion compared to other Hammer options that may be smoother.

Can the coverstock of the Hammer Pure Envy be adjusted for different conditions?

Yes, the coverstock can be adjusted to match specific lane conditions. The 500, 2000 Siaair finish provides strong traction on medium to heavy oil patterns, but you can sand the ball further for more hook potential or polish it for a cleaner reaction on less oily lanes. Adjusting the surface allows the Pure Envy to adapt to various playing environments.

Is the Hammer Pure Envy suitable for bowlers with high rev rates?

Absolutely. Bowlers with high rev rates will benefit from the low RG (2.505) and high differential (0.053) of the Launcher Core, which allows the ball to rev up quickly and generate a powerful, continuous motion. The Pure Envy provides control without losing energy, making it a great option for rev-dominant players who need strong mid-lane traction and backend motion.
