We'd like to take full credit for how well this top came out, but this time serendipity gets most of the credit. We fell in love with the hybrid fabric: a mix of thick, thirsty cotton, wicking poly and spandex. Then we stumbled across this modified polo design that, thanks to the spandex, fit each of us just right and behold, the SerendipiTee. 5" zipper. Fit is relaxed. Only at T9. S(4-6), M(8-10), L(12-14), XL(16)
