Fleece blankets are made from tightly woven polyester that can come in many colors and textures.
A wool blanket is an insulating blanket made from a synthetic fabric blend. The term “wool” often causes confusion because it is sometimes used to describe part of sheep’s wool. In this context, however, it refers to a specific polyester fabric without any wool content. Polar fleece is the best-known type, although there are several varieties available.
Fleece is a great material for blankets because of its excellent weight-to-insulation ratio.
The fabric of this type of blanket is made by taking a polyester thread and twisting it tightly. The resulting material is then brushed with rough wire to tighten it and raise the surface a little, and then cut to level the whole thing. Virtually all types of fleece blankets are made with a high quality fabric known as non-pill, which does not roll up after being washed a few times. In general, the surface texture of this material is more pleasant than other types of wool.
Wool blankets are usually made from polyester yarn.
Good blankets can come in a wide variety of textures, each rendered slightly differently. The top side can be almost smooth or it can have a nice velvety feel, while the bottom side is usually even smoother, with a texture very similar to felt. Many people make their own blankets because of the ease of using wool as a “seamless” material. Beginners tend to like this fabric because it never unravels like most others, making it difficult to spoil.
There are three main weight categories of wool that can be used in a blanket, depending on how warm the manufacturer wants the final product to be. Microfleeces are the lightest and are not suitable for anything other than a light blanket intended to be worn under a heavier one. Hundred-weight wool is the next weight category and is almost as heavy as a pair of regular sweatpants. Medium-weight wool is often used in jackets and vests and is ideal for blankets used in cold weather.
Fleece is a great material for blankets because of its excellent weight-to-insulation ratio. It’s soft and comfortable, retains heat well, and is light enough to carry in your backpack or stash easily in a closet. In camping situations, polyester helps wick away moisture and keeps campers drier than other blanket materials. While perhaps not as ideal as some high-tech alternatives, fleece offers a lot of benefits for a low price.
