This is an old-school swim short constructed with a zip fly, a mesh liner, and a little bit of hidden elastic at the sides for an easier, more secure fit. This gives a clean, flat look at the front and back without a lot of bunching. More thoughtful details: an elastic locker loop at the back, a back pocket with a drainage hole, and trapunto stitching on the waistband for a bit of refinement. At 4.5", the inseam on our Standard is pretty short — we told you, retro — but if you prefer more coverage, the Mid-Length is for you. This pair is made of lightweight nylon in Portugal.
