core tumble shorts

Materials vary by style: recycled polyester (examples include 85% recycled polyester/15% spandex and 100% recycled polyester), nylon/spandex blends (e.g., 79% nylon/21% spandex), and some styles list a 100% cotton lining.

Available inseams across the styles include 2.5", 3", 4.25", 4.5", and 5".

They come in mid-rise and high-rise fits, with waist closures that are either pull-on or full elastic waistbands.

Styles use both midweight and lightweight fabrics — specifically midweight interlock (nylon-spandex interlock) and lightweight recycled polyester poplin.

Some styles include a 100% cotton lining; product listings explicitly note this as “Material Lining: 100% Cotton.”

Common features include flat seams, built-in briefs, pull-on or full elastic waists, and moisture-wicking/quick-drying fabrics on some styles. Design details can include a dolphin hem on run shorts.

Care varies by style: most list machine wash and tumble dry, while at least one style specifies machine wash and line dry or lay flat to dry.

Available lengths include short bike/tumble shorts and above‑knee run shorts.
