We are totally obsessed with this new fabric from Rundholz Black Label, a lightweight stretchy cotton woven with subtle texture that feels like comfy athleisure, but looks all business. It lends itself beautifully to Rundholz's more tailored designs, such as this go-to jacket. It has a zipper placket in front, with a banded collar and extra-long sleeves; pockets sit on the hips. Tailored in its fit, we find it is running true to size.
