There's so much to explore in the winter, so we suit up in waterproof shells, but not before slipping into the Smartwool Intraknit Thermal Merino Baselayer Bottom. These midweight baselayer tights keep us ultra-warm for snowshoe hikes and resort adventures. Merino wool offers its thermal magic, keeping us simultaneously warm and sweat-free. And Smartwool's innovative Intraknit technology enhances breathability and dry times for maximum comfort while we're on the move.
