On those cool evenings in camp or just for lounging around the house, there is nothing nicer than throwing on a soft pair of fleece pants. They’re fluffy, warm, and the lighter weights of fleece and very breathable. Lightweight fleece pants also double nicely if you need an extra layer underlayer during extremely cold weather. Fleece is made of polyester with many brands utilizing recycled plastics that is extruded into fine fibers then woven into fleece cloth. Because it’s made from plastic, fleece is naturally hydrophic (water repellent), so fleece (unlike down or cotton) will keep you warm even when it’s wet. Best of all, it’s machine washable, so if you’ve spent the weekend by the campfire, you can simply toss your fleece pants in the washer and lose the smoke and dirt. How do you choose the right pair? Here are three tips that will help you choose the right pair of fleece pants for the outdoor activities you enjoy.
