Most rompers and jumpsuits in the set are described as midweight fabrics, with a smaller number of options noted as lightweight in the item details.
Many styles include front pockets and some also have back pockets. Other functional features shown include adjustable or drawstring waists, attached hoods, button-front/Henley details, and multiple utility pockets on work-style garments.
