A soaker pad is the absorbent layer of an All-In-Two or Hybrid diapering system. Soaker pads snap into the diaper shell, together forming a complete diaper. Soaker pads are available in a variety of materials to help fit the budgets and needs of different families. There are inexpensive soakers made of synthetic materials, bamboo, cotton and hemp blends, and organic cotton. There are also disposable soaker pads (also sometimes called inserts) designed for one-time use. The budget and diapering needs of a family will help determine which is best for them, but the flexibility of the All in Two and Hybrid design is behind the popularity of soaker pads.
