Carhartt Mens Zip Front Rain Defender Hooded Sweatshirt. Made of 13-ounce, 80 percent cotton and 20 percent polyester fabric. While cotton is soft and pleasing to the touch, polyester is abrasion-resistant, resilient, and quick-drying. The two materials blended together are durable, more wrinkle-resistant, and will shrink less than 100 percent cotton. Rain Defender DWR finish makes this sweatshirt rain-, mist- and snow-resistant to keep you comfortable when you``re working. Rain Defender will stay effective through at least 20 washes.
