Most boys' t-shirt packs are made from cotton or cotton/polyester blends. Listings often specify 100% cotton, a 50/50 cotton/polyester blend, or polyester-based novelty fabrics.
Typical pack sizes are 3-packs, 4-packs, and 5-packs, with exact availability depending on the brand and style.
Fabric weights typically range from lightweight to midweight. Many listings highlight breathable fabrics, and some note moisture-wicking properties for active wear.
Most listings recommend machine wash and tumble dry. Some brands advise washing in cold water, and reviews sometimes suggest flat-drying to reduce the risk of shrinkage.
Most sets are short-sleeve crewneck tees. Lengths are typically described as at the waist, at the hip, or slightly below the waist.
