I picked these pants because they are comfortable joggers, and with a warm fleece lining> It is a thick lining. But most important, these jogger pants have a Front Fly Zipper. That is critical and more jogging pants for men should have a zipper opening. The pants do not lose their form shape if worn a few days. They stay in shape and continue to look good. Great jogging pants. with a zipper and cozy comfortable warm lining!
