This is Aero Tech Designs’ Men’s USA Classic Compression Short in black, an unpadded 84% nylon / 16% spandex short with four-way stretch and anti-chafe construction. The light compression insulates and supports working muscles.
It runs, lifts, spins, and hides under loose shorts or skirts-of-armor alike — the multi-sport layer that outlasts cheap compression gear wash after wash.
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.
