boardshort fabric

Does anyone know what the name/blend of fabric modern boardshorts are made out of and if there anyplace to buy it online?

There’s quite a few different ones, from Supplex to Spinnaker Nylon, including canvas. Some of the patterns, prints and so on are probably proprietary ( a little inadvertent alliteration ) , the fabrics themselves in various solid colors are easily available. Try to start with, they specialise in ‘outdoor’ fabrics for garment and accessory use.

hope that’s of use
