All About Wool

Why Wool?

Wool diaper covers have been around for hundreds of years, but are only now regaining in popularity as more people become concerned with the environmental and financial impacts of disposable diapering.

Wool is a renewable, and healthy alternative to plastic or PUL diaper covers. Wool breathes great keeping baby cool and dry and preventing diaper rash. When cared for properly (occasional lanolizing and gentle washing) it is a great moisture barrier since it is able to absorb up to 40% of its weight in water before feeling wet. High performance athletes have chosen wool because of it's great temperature and moisture regulation properties.

Wool diaper covers do NOT need to be washed every time they are used. The natural properties of wool prevent odors and bacterial growth. They only need to be washed every week or two or when they are soiled. Simply hang damp covers to dry and use them again! The lanolin in wool neutralizes urine leaving a fresh-smelling, leak-resistant cover time and again.

Wash in cool to warm water with a detergent made for wool. Every second or third washing you should add a dime-sized amount of all natural Lanolin (you can use Lansinoh or PureLan if you have it) or a Lanolin product made specifically for wool such as MamaBear Wool Wash.

A great thing about wool wraps is they enable you to use ANYTHING as a diaper, save money by laying in soft absorbent dishtowels, folded receiving blankets, old t-shirts, any absorbent material you have on hand! Snap, velcro, or pin the cover and voila! The cover holds the soaker in place.


Because MamaBear covers are one-size fits all you could potentially spend less than $100 on MamaBear wool wraps and take care of all of your little one's diapering needs using soaker materials from around your house! With care these covers have been used on two or even three babies, tripling your savings!


All MamaBear wool items are washed and lightly lanolized upon completion so that when you get them they are ready for your BabyBear to wear right away.


Wool Weight/Thickness

The "weight" of the cover refers to the thickness of the wool. In general the thickness of the wool deterimines it's leak protection. The thicker the cover, the longer it will last and/or more liquid it will hold before it leaks. Some lightweight or midweight covers made from very dense, finely knit or woven wools can provide the same level of protection as much thicker, bulkier covers.

Thick/heavy covers are really great for very heavy wetters, overnight, long car rides, etc. any time compression leaks (leaks through the cover from a SOAKED diaper) are likely. They are generally too thick to go under fitted clothes but work great under pj's, skirts, and sweats.

Midweight covers are great all-purpose covers. They are trim enough to go under most clothing but thick enough to work for overnight and naptime for most babies. These are what I generally recommend for first-timers to wool unless they know they have a very heavy wetter. Even if you're babybear generally leaks through covers, you can still use midweight and just bolster the absorbtion of your diaper by adding a soaker layer down the center.

Thin/lightweight covers are just that. These fit best on little babies and newborns because they are not bulky. In general they require frequent changes to prevent leaks although some trim wools actually provide very good protection. These include Merinos (which are ultrafine wools and so are densely knit yet lightweight) and Meltons (a dense, spongy, felted wool similar to what you find in outerwear like Pea Coats).
