Most liners are afterthoughts, only there to provide larger jackets with extra insulation. This model from Reigning Champ is an exception, stylish enough to be worn on its own but still capable of connecting to an outer layer. Its shell is made from recycled nylon, with responsibly sourced 700 down fill power insulation in horizontal channels. Primaloft insulation is used in the shoulders and sleeves, while split welt handwarmer pockets and an interior chest pocket provide storage and added warmth.
