Designers notes:

BURGH is Riz's mid-length boardshort; your go-to short for yoga, surf or the sea. Cut with an ergonomic waistband and no side seam, it is arguably the most flattering fit they do. The simple detailing and mid thigh length gives Burgh a semi retro feel. 

This brand runs quite small - we recommend going one size bigger than your normal fit; all Riz shorts tend to be more fitted than your regular boardshorts or swimshorts. If in doubt, size up.
