Sleepwear
Cotton-forward children's sleepwear without added chemical flame-retardant treatments.
The correct fit is part of the safety design of snug-fitting cotton pajamas. We assess fabric and treatment information together with the garment's sleepwear labeling, and do not suggest sizing up for extra looseness. Follow the manufacturer's sizing and care directions rather than using any cotton garment as sleepwear.
