The Fjallraven Abisko Sun Hat is crafted from lightweight and well-ventilated stretch fabric which is perfect for hiking in warm and sunny climates. The wide brim provides additional protection from the elements providing shade for the face, neck and ears. The fabric means you don't risk overheating and the adjustable chin cord prevents the hat from taking flight if the wind gets up. Made from 100% polyester – 70% of which is recycled.
