No. A kilt is not a "skirt" in the sense to which it is applied to women. It is however, still the basic construction of modern kilts, which are not the 8 yards of wool any longer. They are a completed garment more on the lines of skirt construction. And, they are widely available on numerous online outlets, including Amazon. They are also available in a variety of fabrics other than wool. In addtion, worsted wool, which is used in men's suits, is not as hot as other kinds of wool – it's the type of material used in most parts of the world for men's suits. Even in centuries past, kilts were not made of the same weight of wool as overcoats.

I happen to be of Scottish ancestry and have a piece of worsted wool fabric in my clan tartan. It is not heavy material at all. The heaviness or lightness of the fabric has more to do with the spinning and weaving than with the type of fiber. I also have a degree in fashion design with a class in men's tailoring and several in textile and costume history and development.

Also, a modern kilt – worn by the likes of Harry Styles, David Tennant, Kieth Urban, John Barrowman, Will Smith, Kiefer Sutherland, etc. – uses around 3 or 4 yards, depending upon the size for that person. It's a much more streamlined garment than the historical kilt of which you're thinking.
