This black Sweaty Betty Pacesetter running vest is made of a lightweight fabric with sweat-wicking and breathable properties. Cut for a loose fit, this style has a round neck, wide racerback and curved hem. We’ve been considered 'trendsetters' our entire lives – all the other babies wanted whatever dummy and onesie we had. Being 'pacesetters' in this Sweaty Betty top can’t be that different, surely.
