Crafted from 100% extra-fine merino wool.

The Cooper Sweater features our signature slim fit.

A mix of a textured, novelty stitch and a flat stitch create an interesting and subtle design. 

Design Details

We make things that will last. Life isn’t disposable, so we don’t make disposable things. It’s no good if it only looks good. It needs to perform, too. Pieces that last longer than a moment, beyond a season. We design for a long life because we value a life well-lived.
