The Patagonia Quandary Brimmer Hat features a wide, semi-rigid brim that floats and includes a dark underbill to help reduce glare and shield the eyes from harsh sunlight. Designed for breathability and comfort, the vented crown is lined with internal mesh to promote cooling airflow. An adjustable chin strap ensures the hat stays in place even during windy conditions, while a toggled strap at the back allows for a snug fit in active or unpredictable weather. The lightweight, low-profile sweatband enhances moisture and temperature control and is treated with miDori bioSoft for added wicking performance and softness.
