How long are the board shorts? (Knee length?)

They usually hit mid-thigh. The trend has shifted away from longer, knee-length shorts to a sportier mid-thigh cut.

Do they have the mesh netting inside?

Yes, for support. Most swim shorts come with a built-in mesh brief. If it chafes, many boys simply cut it out and wear fitted trunks underneath instead.

Do older boys wear Rash Vests?

Yes, especially for surfing. To keep it looking cool, choose a branded style or a plain black or navy vest that feels more like surf gear than a “kiddie” sun top.

Will chlorine fade the neon print?

Rinse it immediately. Neon dyes are sensitive to chlorine, so rinse with fresh tap water straight after swimming and let it dry in the shade to help preserve the colour.

Can he wear these as casual shorts?

Yes, look for “hybrid” shorts. Many boardshorts are designed to look like casual shorts and come with pockets, making them perfect for heading from the beach straight to the shops.
