All in One (AIO) cloth diapers are most similar to disposables as they have integrated absorbent layers. AIO diapers have a laminated outer shell to protect clothing from moisture.  

Washable diaper covers are great for all types of families.  Diaper covers do not have integrated pockets or absorbance. They are made from a layer of laminated fabric.  Most have adjustable rise and waist snaps. They can be used to cover a range of washable absorbent inserts or over disposables diapers.  Adding a cloth diaper cover can protect clothing from blowouts and compression leaks.  

Microfiber Boosters are the more cost effective options for diaper inserts.  They are made from 100% synthetic fibers and very absorbent. They work best in conjunction with a natural fiber insert.  Microfiber absorbs quickly and due to the nature of the fabric you should not put microfiber against the skin.  Add a layer of fleece or use a pocket diaper.

Hemp cloth is made from the long fibers in a hemp plant stock.  The fibers are mixed with cotton fibers and woven into a highly absorbent fabric.  Hemp inserts work well behind synthetics. These are the most absorbent inserts but also take longer to wash and dry. 

Bamboo and Cotton inserts are made from a synthetic rayon made from cellulose extracted from bamboo the fibers are mixed with cotton fibers and woven into an absorbent fabric.  

Flour Sack Towels (FTS) as 100% cotton rags can be used as cloth diaper absorbency.  Cotton is a great choice for children that have sensitive skin.  A FST can be folded into a pad or wrapped around the infant.  FSTs are the most cost effective way to cloth diaper a baby.
