{"product_id":"callaway-golf-2019-big-bertha-iron-set","title":"Big Bertha Iron Set I6522","description":"The new Big Bertha 2019 irons, combine Callaway's cup-face design with a new internal, multi-material weight system to boost performance. The thin, cup-face design helps spread the sweet spot across a larger portion of the hitting area. Slower-swinging players not only will gain distance on solidly struck shots, they will maintain ball speed more effectively on mis-hits because the face flexes more efficiently at impact. To create a higher launch and further increase forgiveness, Callaway designed each Big Bertha iron with what the company calls a Suspended Energy Core. It is comprised of a uniquely shaped, metal-injection-molded (MIM) internal tungsten weight that pulls the center of gravity lower and away from the face. That promotes higher-flying shots. This results in enhanced ball speed and higher launching shots with better sound and feel. Satisfaction and authenticity are guaranteed.","brand":"My Store","offers":[{"title":"Default Title","offer_id":54351002272060,"sku":"P353532652780919808","price":31.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0994\/9875\/4364\/files\/6ae3f66d7b28d7d23e4f076c429d4c1215c1c103f9c9ca8ed5d83e07097bf1ea.jpg?v=1788659161","url":"https:\/\/yqsnyjs.sbs\/products\/callaway-golf-2019-big-bertha-iron-set","provider":"My Store","version":"1.0","type":"link"}
