The N-Ferno Unisex 6480 Midweight Base Layer Bottoms are designed for comfortable warmth in cold conditions. Made with lightweight and breathable stretch fabric, these pants are a great base layer 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, these unisex bottoms from N-Ferno are a no brainer. Designed with smooth and stretchable fabric for easy layering under work pants and bibs, and an elastic waistband, these bottoms offer 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, these bottoms are the perfect addition to your workwear wardrobe. Flatlock seams and a tagless interior means no irritation and chafing. These base layer pants are ideal for those working in construction, transportation, warehousing, refrigerated areas and more.
