We designed the CourtViper™ Series One line as the first ever compression pant specifically engineered to the needs of ladies' performance tennis. We agonized over fabric content and what the right amount of Lycra® should be. We lost sleep over mesh vent placement and the effectiveness of the MoveDry™ moisture wicking fabric. We checked, re-checked, and checked again the durability of the double reinforced flat lock seams. And of course, we play tested the patented SlipQuick™ pocket technology endlessly. There's nothing like it in the world and we think once you wear a pair of CourtVipers you'll never look back.
