The "grindle" weave is a special process where several contrasting colors of yarns are interwoven to create a salt & pepper effect. This season Grayer's introduced a range of plaids that deliver a bit more character with contrasting colors and hues. At 5.5 oz, these are our lightest weight twills of the season. These subtle tonal plaids can be worn casually with denim and chinos or elevated under a casual blazer. What makes them even more special? Grayer's weaves their own fabric.
