Weighing in at approximately 33 grams, the FLAT TOP grip is 1/3rd the weight of typical putter grips found on the market today. Our proprietary NANO cellular technology allowed us to create a near perfect grip. Hot or cold, rain or shine, the Sacks Parente Featherweight Flat grip is the turbo-charger for our patented Ultra-Low Balance Point Technology.  With exacting standards for feel and comfort that exquisitely balance the levels of tack and cushion, you will know why you chose a Sacks Parente putting instrument.
