AA,
This company, www.duluthtrading.com , has some khaki-colored & navy blue jackets. One version is made of hemp. They're geared towards travelers, but no reason not to convert to kilt length. All of them have more pockets than Carter's has little liver pills.

The only downside I can see is you'll hafta pay full-price for the garment.

Slainte yall,
steve
