This parka requires no complex setup; simply put it on and adjust the zipper as needed. Its long design and synthetic insulation make it compatible with various layering systems. For very cold conditions, wear a moisture-wicking base layer and a mid-layer (like a fleece) underneath. For mild cold, a simple long-sleeved shirt will suffice. To ensure the longevity and performance of your Suttle Mountain Long Parka, proper care is crucial. Generally, synthetic insulated garments should be washed on a gentle cycle with cold water, using a mild detergent. Avoid harsh chemicals or bleach. Tumble dry on a low heat setting with dryer balls to help fluff the insulation evenly. Do not iron. Always refer to the care label inside your specific parka for the most accurate washing instructions. Proper storage involves hanging the parka in a dry place to maintain its loft and shape. Info needed: Specific washing and drying instructions should be confirmed from the product's internal care label.
