There are lots of tartan shirts out there - they go well with a solid color kilt, or when you can't wear a kilt. The tartan shirt lets you express your clan affiliation.

But have yet to find a hot weather tartan shirt - like an aloha shirt in tartan. Why not? Would look great in most any tartan - especially the Hawaiian state tartan.

Guessing it has something to do with the difficulty of weaving the tartan fabric, or imprinting a tartan imprint on plain fabric, to create the tartan aloha shirt.

Bet it would sell in hot climates.
