Cloth Diapering 101: Cloth Diaper Terms

Sizing

Sizing can be different from one manufacturer to another but will usually fall into one of the following categories.

One Size

One size diapers are meant to fit babies from birth to potty training. In general, one size diapers will not properly fit smaller newborn or preemie babies, leading to a gapping diaper and leaking. Many manufacturers who produce a one size diaper also offer a preemie or newborn line to ensure a proper fit for your newborn.

Two Size

Two-sized diaper systems are designed to effectively diaper your baby from birth to potty. In an effort to maximize the fit and affordability of cloth diapering your baby, Thirsties created the Duo line of products. Size one fits babies between 6-18 lbs, and size two fits babies from 18-40 lbs. Each of the two sizes in the Thirsties Duo line feature three rows of snaps to adjust the rise to your baby’s shape, it is like having three sizes in one.

Sized

Sized diaper systems offer a specialized fit for your baby, but each size covers a narrower range than that of a Duo or One size system. Thirsties Diaper Covers are part of a sized system and are available in four sizes, x-small, small, medium, and large.

Components

Hook and Loop Closures

Hook and loop closures make diaper changes quick and provide an amazingly snug fit. Although hook and loop closures are the most convenient closure option, they have a shorter lifespan than snaps. Thirsties products use Aplix(R) brand’s hook-and-loop system which is made in the USA and is regarded as the most durable on the market.

Snap Closures

Snaps are easy to use, are more durable than hook and loop and are strong deterrents to toddlers who prefer to be diaper-free. Snaps are also used throughout the Duo line on the adjustable rise.

Gussets

Gussets are a crescent-shaped inserts added to the leg openings of many cloth diapers for added performance and expansion. Thirsties signature leg gussets move with your baby, providing advanced protection against leaks.

Fabrics

PUL

No stuffy plastic or rubber pants! PUL provides a very reliable, pliable, and breathable yet waterproof outer layer for Thirsties’ covers, wraps, and diapers. PUL stands for polyurethane laminate and is made from extremely durable polyester knit to keep your baby and his or her clothes dry.

Microfleece

A soft, napped wool-like fabric made from synthetic fibers. Microfleece fabric does not absorb, but rather allows moisture to pass right through, which is why it is often used as the layer closest to your baby’s skin. The microfleece layer provide a ‘stay-dry’ effect for your baby’s comfort. Microfleece can help to reduce diaper rash, resists staining, and is buttery soft to the touch.

Hemp Jersey

Hemp jersey is as soft as your favorite t-shirt but is more durable than pure cotton of the same weight and absorbs 25% more moisture! By using hemp, you are able to gain a substantial amount of absorbency without adding a tremendous amount of bulk to your diapering system. Thirsties hemp jersey is one of the softest and most durable available in the market. It is used in Thirsties prefolds and inserts.

Microfiber Terry

Our synthetic microfiber terry is used throughout our line as a soaker due to its performance characteristics of being highly absorbent and quick drying.

Cotton Velour

This velvety fabric is a cotton/poly blend that is absorbent, luxuriously soft and custom knitted and dyed to Thirsties specifications. It is used in Thirsties’ fitteds, doublers and wipes.
