What type of fabric is the underwear made of?

Outer Layer (Waterproof):

Made from PUL (Polyurethane Laminate)

• It’s soft, flexible, and fully waterproof—designed to keep moisture locked in without the crinkly feel of plastic or rubber
• PUL also allows for some breathability, which helps reduce heat buildup overnight

Inner Layer (Against the Skin):

• Made from a smooth athletic wicking jersey or stay-dry polyester fabric, depending on the style
• Designed to help wick moisture away from the skin while still allowing the child to feel wet for the first few moments (in Brain Trainers), which is crucial for brain-bladder training

Absorbent Core (Built-In + Inserts):

• Made from microfiber, which is super absorbent and dries quickly
• We use multiple layers inside the underwear to soak up accidents while keeping the bulk manageable
