Fitted diapers are a great option for overnight use because they have 100% absorbency, but they can also be used during the day without a cover for a period of time but will eventually become damp. A PUL or wool cover is recommended to be completely waterproof.
These diapers use a fold over rise system and large fold over wings that allows the diaper to be adjusted from infant to potty. Approximately 10 to 40 lbs.
Hybrid fitteds are made with a hidden layer of polyester fleece which adds a mild liquid barrier while maintaining breathability.
The outer diaper is a cotton knit; the inner diaper is either cotton or bamboo velour. The hidden layer consists of either bamboo/hemp fleece (regular fitted) or polyester fleece (hybrid fitted).
A sandwich-style snap-in soaker consists of two layers of bamboo/hemp fleece with matching velour on top. A matching contoured booster is included with each diaper that matches the outer diaper and consists of a layer of Zorb and a layer of bamboo/hemp. When using the booster, place it on top of the sandwich soaker with the printed side closest to baby.
All fitteds use comfort elastic casing for all elastic points. This prevents red marks on little legs. Standard casings or ruffled casings are used. Picture below shows a standard casing through the legs and ruffled casing at the back.
