Fortera™ Exile

Available June 27, 2014


The all new Fortify reactive coverstock is Brunswick’s hottest creation based off our performance enhancing additive chemistry technology. Fortify reactive combines a new base coverstock with an enhanced additive package that will provide the easiest length with the quickest lateral traction of any coverstock to date.


The Fortera Flip core incorporates a new shape for an enhanced breakpoint and extreme continuation. The core is dynamically calculated to extend the rotational energy, boosting angular velocity to transfer energy to the pins for increased pin action and higher scores.


Finished with Royal Shine polish, the Fortera Exile skids effortlessly through heads, with an unprecedented backend flip providing an incredibly powerful ball motion on medium to oily lane conditions. A new ball motion never seen before in the Brunswick line.


The Fortera Exile can be drilled using the standard drilling techniques developed for asymmetric core bowling balls.


At Brunswick, the unique core shape of each individual ball is used for weights from 14 to 16 pounds. This approach to lightweight ball engineering provides bowlers with consistent ball reaction characteristics across this weight range. At 12 and 13 pounds, Brunswick uses a generic core shape with a RG-differential that is close enough to the 14 to 16 pound shape so the same drilling instructions can be used.
