The Aptitude Jacket leverages waterproof/breathable Isotex 15,000 performance stretch fabric with Thermoguard insulation to keep them warm, dry and comfy in cold, wet weather. The shell uses a seam-sealed polyester stretch fabric with a DWR (Durable Water Repellent) finish to deliver waterproof, windproof and breathable protection that’s soft and comfy to wear. The adjustable hood, hem and cuffs provide a closer fit when needed. Zipped pockets secure essentials. With reflective trim for low light exploring and our signature R on the chest.
