How Much Warmer Is Fleece vs Cotton?

When it comes to warmth and insulation, there’s a noticeable difference between fleece and cotton. Fleece is specifically designed to be warm and provide insulation to the wearer. It’s double-sided pile construction allows it to trap a significant amount of air next to the body, creating a layer of insulation. This trapped air acts as a barrier, preventing heat from escaping and cold air from entering, making fleece an excellent choice for cold weather conditions.

On the other hand, cotton has very little insulating ability. It lacks the properties necessary to effectively trap air and retain heat. Cotton is breathable and lightweight, which can be advantageous in certain situations, but it isn’t well-suited for providing warmth in colder climates. In fact, cotton has a tendency to absorb moisture, such as sweat or water, which can further cool the body and reduce it’s insulating qualities.

Fleeces double-sided pile construction traps air to create a layer of insulation, providing warmth while remaining breathable.

The Different Types of Fleece and Their Varying Levels of Warmth

Fleece is a type of fabric that’s commonly used in insulating layers of clothing. It’s known for it’s warmth and insulation properties, making it a popular choice for outdoor activities and cold weather conditions.
