Large Quince Our 100% Merino Wool Shirt Jacket - used but in good condition, with pilling on the inside of the jacket. Expertly tailored with boiled merino wool, this shirt jacket - shacket - has the relaxed silhouette of a shirt, but provides the warmth of a jacket. With an intentionally oversized look, it's perfect for layering and made to throw on over any outfit with ease.
