Sunday Afternoons

Frequently Asked Questions

• What level of sun protection do Sunday Afternoons hats provide?

  All Sunday Afternoons hats carry UPF 50+ sun protection, and many combine that rating with wide-brim designs (typically 3½"–4") and optional neck capes (6"–7½") to block UVA/UVB exposure to face, ears, and neck. UPF ratings are based on lab testing of the fabrics rather than implied by color or weave alone.
• How does the Ultra Adventure Hat compare to the caped sun hat styles?

  The Ultra Adventure Hat is positioned as the highest-performing, technical option—optimized for high-output activities with a streamlined profile and award recognition for technical use. Caped styles prioritize extended coverage with a 6"–7½" neck cape and safety features like the Breakaway SmartStrap™, making them better for long days where neck and ear protection are a priority.
• How does CoolCore® fabric technology work and when should I look for it?

  CoolCore® is a patented, chemical-free cooling technology built into the fiber that enhances wicking and accelerates evaporative cooling to help you feel cooler during high-output activity. Look for CoolCore® spec listings on models intended for intense sun exposure or active use if you prioritize added evaporative cooling.
• What should I consider when choosing size, brim width, and model for hiking versus casual use?

  Sunday Afternoons hats feature adjustable sizing for a customized fit—use adjustments and hat fit charts when available to match head circumference and retention needs. For hiking and high-output activities choose technical models like the Ultra Adventure Hat or wider-brim technical styles for stable protection; for low-impact, all-day leisure choose styles with slightly wider brims or caped designs if extra neck coverage is desired.
