I prefer the Professional. They're not really like the TS breech fabric--more of a microfiber. They are sturdier, hold their shape better and repel dirt. But they have the clarino knee patches and are machine washable.
The Supremes are a sturdier fabric and have the nice leather knee patches if you like that.
The fit is also different. The Supreme is more of a relaxed fit, so if you like more give, you might prefer it. The pros are similar in cut to the TS breeches, IME.
Can I ask a silly question along the same lines? I know most people wear the beige breeches- Is any color beige acceptable? Some are lighter in color and some almost have a greenish/brown dark khaki color. What do most people wear?
Giddy-up, I have both and definitely prefer the Professionals. The fit and fabric is more similar to the schooling breeches, but has a nicer finish (and I like the color a bit better). I find the Supremes to be really stretchy...meaning they show lumps and bumps a bit more easily.
