This pant is a great all around pant. With built-in Thermacore insulation, they are warm on the days that are colder than we would like. I wear these pants on moderately cold days, around 20 degrees, and I am perfectly warm. Sometimes insulated pants can be slightly inflexible; however, this is not the case. They are comfortable, the fit is great, and they allow unrestricted movement. Breathability is awesome, as they feature zip vents on both the inside and outside of the thighs. They have four pockets (two in front and two in back). The fit and style resembles a pair of jeans. There are various color choices, too.
