Ocean & Earth Boys Anti-Rash Surf Short Apparel

These go under boardshorts or a wetsuit so skin doesn't get rubbed raw. It's a common problem for kids: two hours on a board, wet fabric and salt, and by evening the inner thigh stings enough that tomorrow's session gets skipped.

The key detail is the absence of side seams. It isn't the fabric that chafes, it's the seam — stiffer than the cloth and sitting exactly where the leg meets the board. Remove the seam, remove the cause. The nylon/elastane blend stretches in every direction.

The waistband is soft elastic with no drawcord or buckle: under a wetsuit any hardware becomes a pressure point.

Who it isn't for. These aren't swim shorts — they're a base layer. They add no warmth either: for a cold kid you want a fleece-lined thermo, not thin nylon. And the sizing is boys' only.
