Hybrid diaper systems are becoming increasingly popular. These typically have a waterproof diaper cover and are combined with a soaker. The soiled soaker can be removed and replaced with a dry soaker after use, and the cover can be reused, lessening the amount of diapers needed. It’s much cheaper to buy less covers and more soakers/inserts. Some hybrid systems come with disposable inserts, which is convenient for traveling. Green Line Diapers is an up-and-coming company that makes unique and trendy covers, as well as soakers.
