Our exclusive research partner, Hot Stix Golf, used a Shore D Durometer tester to measure cover hardness for every ball in our test. We took the average of five measurements on each ball. The Shore D hardness scale is commonly used to gauge the hardness of plastics and rubbers. (A lower Shore D number equates to softer.)
