I wear this Pickleball Bella Lobster Monster Racerback Tank for weekly matches and it has held up well. The racerback cut gives me a full range of motion on overheads and drives, and the scoop neck stays comfortable. Fabric is 86% polyester / 14% nylon with moisture-wicking and anti-odor tech, plus 50+ UV protection for sunny courts. It stretches without feeling loose, and it matches the Pickleball Bella skirts. Sizing ran true for me in a medium.
