Winters can get rough and cold. These thermal long johns will help you make it through. They are silky on the outside but lined with soft thermal fleece on the inside. They fit snug enough that there is no bulkiness showing when worn under clothes-even underneath jeans. They are also wonderful to sleep in. These sets will continue warming you even after being laundered many times.

These Rocky Fleece Lined Thermals are well designed for wear under your clothes OR alone. The perfect base layer, they can be worn under running and jogging clothes, or for cycling, skiing or any other outdoor winter sports activities.

They can also be worn under your casual or formal attire such as under your jacket, sweater or hoodie without adding any bulk or visible crease lines in your clothes.

The waist of the pants is elastic for a comfortable snug fit. Both top and bottom are stretchy, perfect for activewear. These light-weight thermal pants make all the difference in the world.
