This is Aero Tech Designs’ Men’s USA MTB Short in charcoal, a two-part system pairing a rugged 100% nylon shell with a padded mesh liner running the BKP crotch pad — smooth-faced, ventilated, and rated for three-to-five-hour rides.
It takes trail days and casual rides in stride: hand pockets hold keys and a phone at the trailhead, the seamless crotch area removes saddle rub, and the soft wide waistband with 3M Scotchlite accents keeps it comfortable and visible. An 8-inch shorty inseam and sizes to 5XL cover the range.
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.
