Double Brushed Poly is one of the main fabrics we use in our shop, because of the soft buttery feel and amazing stretch. It is exempt from lead testing: 16 CFR Part 1500.91(d)(7)(ii) and flammability testing: 16 CFR Part 1610.1(d)(1). It’s not breathable like fabrics with natural fibers, since newborns/small babies cannot regulate their body temperature it’s not ideal for them to wear. If you decide to purchase clothing for small babies made out of DBP please keep an eye on them at all times. If they start to show signs of overheating immediately take the clothing off!
