The L3 Warm Fleece Underwear Jacket is a good design for Military Army Training and outdoor sports. It is made of soft fleece, keeping warm and comfortable in cold winter. You'll enjoy free range of motion and drawcord at the waist, bottom, and hood offer added protection and warmth. It can also be used as a warm lining, matching the professional waterproof outdoor jacket.
I find this to be a excellent addition to my layering pieces when its cold.
