Is Polar Fleece Waterproof?

Polar fleece is not inherently waterproof. It is primarily designed for its insulating and moisture-wicking properties, which make it a good choice for providing warmth and comfort in cold or wet conditions. While fleece can resist and repel light moisture, it is not waterproof or water-resistant to the extent that it can keep you completely dry in heavy rain or when fully submerged in water.

However, there are variations of fleece that are treated with a water-repellent finish or combined with other materials to enhance their water-resistance. These specialized fleece materials are often used in outdoor and activewear, where some degree of water protection is desired. They are not completely waterproof but can provide protection against light rain or moisture.

If you need a fabric that is truly waterproof for activities in heavy rain or water-related sports, you would typically opt for materials specifically designed for that purpose, such as waterproof breathable fabrics like Gore-Tex or rain-resistant coatings like DWR (Durable Water Repellent) on outer layers. These materials are designed to keep you dry in wet conditions by preventing water from penetrating the fabric while allowing moisture (like sweat) to escape.

In summary, standard polar fleece is not waterproof, but specialized fleece variations may offer some degree of water resistance. If you need significant waterproofing, you should consider fabrics and garments specifically designed for that purpose.
