The world of “fluff” has its own specific language, so before immersing ourselves in this world there are a few terms that need to be defined.
Below you will find words/abbrs. frequently seen in cloth diapering posts.
Fitted diapers that have a waterproof outer layer and the absorbent soaker that is typically sewn in. Fasten with hook/loop or snaps.
Similar to an AIO, but the soaker isn’t attached, so you have two separate pieces which decreases drying time.
Hourglass shaped diapers with no elastic in the legs or back. Not waterproof, so a cover is needed and often wings are fastened by pins or Snappi.
Provide a waterproof outer layer for non-waterproof diapers.
Doublers or Newborn inserts
Pad-like absorbent soaker that can be added to a diaper to increase absorbency or you can use these for newborns to achieve a trimmer diaper.
A countered and fitted diaper with elastic around the legs and back; fastens with Velcro or snaps, but isn’t waterproof, so will need a diaper cover.
One-layer diapers that are like “old-fashioned” diapers; require folding and pinning.
Hook & Loop
Velcro-like closures typically made from Aplix or Touchtape.
Typically a cloth diaper cover that has either a regular insert or also the option of a disposable diaper insert.
Wool soakers with long legs forming pants.
Rectangular shaped diapers that must be folded into the shape of a diaper. They are like flats, but have multiple layers with more layering in the middle. May see descriptions like 4x8x4, which would mean 4 layers in the outer sections and 8 in the inner section. Will need to use a diaper cover over a prefold.
Outer layer is waterproof and inner layer is a stay dry material like microfleece. Closures are either hook/loop or snaps. Have a pocket opening that allows you to stuff an insert, prefold, doubler, or a terry wash cloth. Can adjust overall absorbency by adding an additional layer into the pocket.
One Size Cloth Diaper (OS)
Typically will fit a child from birth up until 30 or 35 pounds.
Polyurethane Laminate (PUL)
Typically used in cloth diapers for a waterproof layer
The measurement from the top of the front side of the diaper, between the legs and to the back edge of the diaper.
Wool soakers with short legs forming shorts
A T-shaped plastic fastener used to fasten diapers instead of pins.
A process to remove buildup from a cloth diaper.
A diaper cover made out of wool.
