The Thermal Insulation Long Shorts W are a pair of longer hybrid shorts with a lightly padded front. The padded longer shorts have four-way stretch on the back and a light padding on the front to keep you warm. The outer fabric is woven together which makes the garment very exclusive. Works great as a mid-layer under the shell pants to keep the heat on the thighs, or wear the shorts over a pair of base layer pants during running training in the colder temperatures.
