For the uninitiated, a bit of Haberdashery 101: end-on-end fabric is constructed by alternately weaving colored yarn with white yarn, creating a subtle mini-check pattern with a smooth texture. It's the kind of shirting that belongs in any man's wardrobe, and for the guy who regards his bike as the best mode of transportation, the single best option is this Two-Ply Pivot Shirt from Outlier. The design forgoes the traditional rear arm seam and instead carries pivot sleeves that extend to the back of the garment, resulting in extra side panels for ease of movement. The two-ply cotton shirt features a straight collar, storm flap chest pocket and single-needle stitch throughout. Best of all, it's cut and sewn locally in New York City. Find it in assorted colors at Outlier's online store.
