The N-Ferno 6480 Midweight Base Layer Pants are designed for comfortable warmth in cold conditions. Made with lightweight and breathable stretch fabric, they are a great base layer bottom for keeping workers warm without overheating during high levels of activity. The 240 g polyester-spandex performance material provides warmth without the constricting or bulky feel often found with heavyweight base layers. Made with a soft brushed interior that traps body heat while wicking moisture to keep workers dry. The fabric is smooth and stretchable for easily layering under work pants and bibs, plus an elastic waistband for a secure and comfortable fit. Unlike other base layers, these pants are designed to sit slightly looser on the skin to enhance breathability and provide an air gap for added insulation. Featuring moisture-wicking technology, anti-odor treatment and a breathable mesh fly front to keep workers comfortably fresh, dry and warm all day.
