This open-collar shirt is made from palaka check broadcloth, using 60 single covering core yarn (polyester core wrapped in cotton) for the base and 40 single slub yarn for the stripes. It features a natural wrinkle texture from shrinkage differences and a three-dimensional color effect created by subtle changes in warp and weft thread colors. Inspired by the palaka check used in Hawaiian workwear, it has a hem drawcord for silhouette adjustment and an oversized fit for added comfort.
