Kifaru engineered the Lost Park Parka to be incredibly durable while remaining extremely lightweight. With worldwide success of the Parka we decided to release pants as well. It’s breathable and lightweight fabric is made for the most extreme conditions and use. Kifaru uses Climashield APEX insulation. In an innovative construction process, the insulation is sewn into a tough inner lining to create one consistent layer of warmth that leaves no cold spots that could otherwise be caused by insulation clumping. Protection of your knees/shins and rear are insured with double paneled Cordura.
