I have 3 SWK standards and 3 SWK wools including the wool saffron. It appears that the wool saffron is a lighter color. I ordered SWK saffron flashes and the are somewhat darker than the kilt - they look like they are the same color as the SWK standard saffron.

With all that said, I would go with the wool saffron if you're not going to be wearing it outside very much in hot weather. If you plan to spend a lot of time outside in the kilt when the weather is hot, I would go with the standard saffron because of the lighter weight.
