Wool Covers
Wool is anti-bacterial, breathable, absorbs 30% of it's weight in liquid, and is naturally water repellent. Wool covers can come in a variety of choices. You can use wraps, soakers, longies, shorties or even skirties for little girls.
Wraps
Wool wraps are a diaper cover made of wool. They are made with elastic in the legs and back and have either aplix or snap closures. Wool wraps are great for under clothing and are a great alternative to PUL covers. Wool wraps can also be used at night with your night time diaper for a great breathable night diapering system. Some trimmer soaker materials would be wool jersey or crepe wool. They are a bit on the thinner side, so when using those types of wool, you will want to have a good absorbent diaper. Wool jersey or crepe wool wraps are probably not good for a heavy wetter.
Soakers
Soakers are made to wrap around the diaper and cover only the diaper area. These covers pull on and have not closures. Soakers can be paired with baby leggings or put on under regular clothing. They are a bit more bulkier than a regular PUL diaper cover though, so they not fit under all clothing. Wool soakers are usually made with interlock wool or recycled wool.
Longies
Longies are like a diaper cover and pants in one. You simply pull them on over your diaper and there is no need to add an extra pair of pants to your outfit. You can get longies with either knit, interlock or recycled wool. You can find amazing colors and patterns and match them to cute shirts making some really adorable outfits. Not only that, but it will keep your little warm warm and comfy through all the cold months of the year. If your looking at wool longies, this will be the most expensive type of wool cover.
Shorties
Shorties, much like longies, are just an awesome cover. They are like a cover and shorts in one, leaving you able to avoid finding clothing to fit over your cloth diapers. You can use them all through the warmer months or pair them with baby leggings for when it gets cooler out. Shorties come in a either knit, interlock or recycled wool. You can find tons of bright colorways and fun patterns for the summer months, making it fun to match with tank tops and shirts. Wool shorties are a bit more affordable than longies
Skirties
Skirties are the most fun diaper covers if you have a little girl. A skirty is like a soaker with a skirt sewn in and covering it. The soaker part is the cover and the skirt part is for the outfit. You can even find skirties that have longies sewn in underneath instead of a soaker, which would be great in colder weather. These can be absolutely adorable and come in many sweet and girly colors and patters and can also have ruffles on the bum. You can get skirties made from interlock or knit wool.
