Any product that can be made from wool can also be made with microfleece. Microfleece is a great alternative for people who are allergic to wool, or those with sensitive skin.
Microfleece is also hydrophobic, or water-repellent, making it quick to dry and warm even when wet. When fully soaked, microfleece holds only one percent of its weight in water and remains breathable. Its hydrophobic properties make it good for wicking away sweat, so fleece is a great material for active wear.
