Product listings most often list polyester or acrylic and describe the fabric as a knit construction (some listings note woven constructions).
Fits commonly range from loose and classic to regular. Lengths are often listed as at-waist, with some styles offered as cropped pullovers.
Fabric weight ranges from lightweight to midweight. Several listings highlight soft, breathable knits and mention hollow-knit constructions that improve airflow.
Cuff types include no cuff (straight hem) or ribbed cuffs. Closures appear as pullovers or full button-down fronts depending on the style.
Descriptions indicate they suit transitional seasons and cooler days. Hollow-knit or lightweight pieces are noted as better for warmer or milder climates.
