Different types of outdoor activities call for different types of equipment, and base layers are no exception. From recreational activities like snowshoeing on the local trail to high output activities like running and skiing, picking the right equipment is crucial. Because there are so many different types of activities, we at Garneau developed four levels of base layers, the 6000, 4000, 3000 and 2000 series. Superior warmth coupled with superior stretch makes these 3000 base layers pants a quintessential addition to your outdoor winter wardrobe. Ready to keep you warm on the move, the stretchability offers easy layering without hindering range of motion.
