My first kilt is an eight yard 13oz from the HoE muted line I selected based on colors. The first thing I noticed when I took it out of the box is it is too heavy for serious hill walking. The second thing I noticed is it has a fluid feel to it and in pictures it molds to the body more than many 16oz kilts. You can notice this in aprons or over the thigh when someone has a foot forward in a picture. The HoE 13oz is known to be difficult to press and combined with the lighter weight I don't think the pleats look quite as crisp as some 16oz kilts I have seen.

That being said I love the color and the kilt is extremely comfortable. I wore it all day in Pleasanton with temperatures in the low 90s and was not overly warm. So in conclusion I would say an eight yard 13oz kilt from HoE fabric is neither fish nor fowl. It does not have the crispness of a tank and is not tremendously lighter in weight. If you love the colors then go for it. If you really want a tank or a four yard box pleat look for a 16oz fabric you like even if you like a 13 oz better. Hope this helps. I am on the left in the picture wearing Morrison red muted in 13oz HoE. Panache may chime in but I am guessing from the drape he is wearing 16oz.
