Abstract: Cold weather riding pants are disclosed and are formed of a basic pants structure of a composite of an outer fabric, an intermediate layer of thermal insulation and an inner lining inside of the riding pants. A biaxially stretchable elastic insert is positioned along the outside side of each leg pant as well as in the upper portion of the seat of the pants. A frictional material insert is secured along the inside side of each leg pant together with an adjustable stirrup along the bottom of each leg pant. A pant leg zipper and/or an adjustable strap for gathering the lower portion of each leg pant is used to provide lower pant leg opening adjustment.
