This is Aero Tech Designs’ Men’s Core Padded Cycling Bib-Short in black 83/17 nylon-spandex, carrying the Century chamois developed for 100-plus-mile rides and seven-plus saddle hours: high-density perforated foam under a soft, ventilating face.
It holds together on the longest days — six-way-stretch compression supports the legs, the breathable back mesh panel sheds heat, soft white straps with reinforced binding skip pressure points, and flat-locked seams with a seamless inseam remove the rub.
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.
