The Karma Navy Solid uses a retro Urethane coverstock. Designed for extra length and a smooth predictable ball motion the Karma Urethane is designed for lighter amounts of oil and a more "down the boards" line to the pocket.
The Karma Urethane incorporates a familiar light bulb shape Medium RG Performance core that provides easy length through the heads, mid-lane stability while maintaining axis rotation for a strong continuous backend motion.
With its 1500 grit Siaair Micro Pad finish, the Karma Urethane will still provide good length through the heads with a very smooth predictable breakpoint. The Karma Urethane is great ball for rev dominant and slower ball speed players on light oil conditions.
The Karma Urethane can be drilled using the standard drilling techniques developed for symmetric bowling balls.
At Brunswick, the unique core shape of each individual ball is used for weights from 12 to 16 pounds. This approach to lightweight ball engineering provides bowlers with consistent ball reaction characteristics across this weight range.
