It's the adjustable white and grey logo-jacquard side ties that set The Upside's Issy performance tank top apart - note the tennis racket and ball motifs for a quirky twist. The light-grey design is crafted from a quick-drying fabric and cut with a scoop neck slim shoulder straps and a racer-back with cut-away shoulder while side-hem slits further ease the relaxed fit. Wear yours with similarly hued shorts for a concise workout look.
