The North Face Men’s Aconcagua 3 Vest is a staple for hiking and general outdoor use. Worn under or over other layers, it provides a reliable boost of warmth without restricting movement or weighing you down. The main body comprises a 50/50 blend of 600 fill recycled down and recycled polyester synthetic insulation; the side panels use 90% recycled polyester sheet insulation. The hybrid construction ensures optimal warmth even in damp weather. This vest also features zipped hand pockets and a warm collar to finish the look.
