"This is my second Shak vest and that are the perfect weight and warmth. I sized up as I like a bit of room to wear a sweater underneath. Greta purchase."

Making clothing can be a dirty business, but we strive to keep it clean. Our line is crafted for quality and long-term performance. And we limit what we make: small-batch production ensures every garment is built to the highest standards and finds a loving home. Our approach minimizes landfill waste and uses less energy and water. We know it’s disappointing when a style you love is out of stock, but we appreciate your joining us in our pursuit of the highest environmental standards and carbon neutral impact.

"Their would be my second Shak vest , it’s a great product but the new version is much longer and the fit is bigger than the previous one which I wore with great pleasure and performance for a decade. Make sure you get the right fit or you may be disappointed with a garment that you love everything about it except the fit"

"The shak vest is a very nice 100% wool vest. I wanted something light to mid-weight for work, and this one hit the mark. On my suggestion, my partner got herself a shak jacket to work out, and she really likes it."
