Keep your layers technical with the advanced performance of the Smartwool Men's Intraknit Thermal Merino Base Layer Bottoms. Built for big mountain adventures, these ultra-warm base layer pants power through any expedition thanks to the integrated insulation, articulation, and mesh ventilation of Intraknit™ technology keeping you warm, mobile, and dry through any intense activity. Made with a merino blend, these bottoms are naturally moisture-wicking and temperature-regulating, and with a 3D-mapped design, you get the complete freedom of movement you need on your most rugged jobs, winter hikes, and backcountry ski treks.
