Our years of expedition experience means that we appreciate the role of base layer pants or thermal leggings during those cold-weather hikes. This additional layer under your hiking pants gives you an added layer of warmth and insulation to help prevent feeling cold.

Rab® men's base layer pants are developed in a range of styles using materials such as Polartec and Merino Wool to ensure that there will be something to suit every need. A pair of quick-drying, stretchy, insulating long johns along with a suitable base layer shirts is a must for any cold-weather layering system.
