Are you really sure about this? I do not think this is true, the material usage both seem the same to me. The FL is designed to be a lighter weight and more importantly compressibility. It is an emergency shell and so loses some niceties such as adjustable hem and soft chin guard for comfort. If you're not using as an emergency shell, get the SL.

I’m off to mountain warehouse instead
I think sweat is the reason, but don't quote me on that.
