Polartec ECWCS Gen 2 Fleece Jacket Black. This jacket can be worn as a cold-weather liner for the ECWCS Gore-Tex parka, or as an outer layer. Thicker Polartec fleece is used compared to the Gen 3 fleece jacket, making the black version the thickest and most popular. Features a double-zipper front closure. Ventilation zippers are located under the arms. The left side drawcord is loose and doesn't tighten well. The cord can be adjusted by tying it tighter. Thank you for viewing.
