This multi-purpose waffle-knit thermal layer from Harbor Bay was specially designed at DXL with precise proportions and a perfect Big and Tall fit. It's built with thermal-regulating insulation for heat retention and temperature regulation without overheating, features odor control technology to neutralize bacteria and moisture management technology to help keep you dry. The comfort-stretch fabrication provides superior softness and allows for a full range of motion. The droptail hem is also thoughtfully designed to always stay tucked. Pair it with our coordinating waffle-knit thermal pants for a complete base layer when you're braving the elements.
