If not too keen on a kilt, or you simply want more variety, a skirt might be a possibility. On, say, a hot summer day, an appropriate skirt, worn instead of shorts, could even make more sense than a heavier kilt.

Men's skirts are available, but they are still few on the market. Some nice ones, you might find with Spanish Davesbrand.com. Above, you see a tartan skirt, not a kilt, from the Daves Barker collection.
You could also ask a tailor to make you a skirt according to your wishes, or you might be so gifted that you could even design and make one yourself. Or perhaps your wife or girlfriend could and would. By definition, it should then be a man's skirt.

Alternatively, you might go looking for an appropriate skirt in women’s stores, where you might be happy to find one, which by design, fabric, and colour is manly (enough) and available in your size. But considering how feminine women's fashion has become, it shall be difficult, if not impossible.
