Full length loungewear pants keep you warmer in cool and cold weather months. Completely covering the lower leg, full-length loungewear bottoms keep you warm when the thermostat is set lower to save energy. Most loungewear pants have covered elastic with adjustable front ties for a comfortable fit, and have full flowing legs for non-constricting ease of movement. Favorite fabrics tend to be 100% cotton or cotton blends, super-soft modal with spandex for stretch, polyester fleece or rayon. Many styles also may be worn as sleep pants.
