This is Aero Tech Designs’ Men’s USA Classic Cycling Short in navy 84/16 nylon-spandex. The four-way-stretch knit resists pilling and chafe with light muscle-insulating compression, and the two-panel construction keeps seams to a minimum.
It handles daily training loops and commutes with the Classic perforated chamois breathing through two-to-five-hour rides — a silicone-free elastic leg hem grips without pulling skin, and the non-rolling waistband stays planted bent over the bars.
Aero Tech Designs has designed and sewn cycling apparel at its factory in Coraopolis, Pennsylvania, outside Pittsburgh, since the 1980s, with one of the widest size ranges in cycling.
