A sweatshirt is a type of garment that is commonly worn for casual occasions or during physical activities. It is an oversized pullover that has long sleeves and does not come with a collar. The material used to manufacture sweatshirts is usually a soft, absorbent fabric such as heavy cotton jersey with a fleece backing. This makes it comfortable to wear and provides warmth during cooler temperatures. Sweatshirts come in a variety of styles, including those with graphics and logos, making them popular fashion items as well. The durability and versatility of sweatshirts make them an essential addition to any wardrobe.
