This modular hat system transforms from a basic baseball cap to comprehensive sun protection through detachable components. The base cap features mesh crown panels for ventilation, while the detachable neck cover provides UPF50+ UV protection with adjustable straps. The full-guard mode adds a breathable mesh face mask using magnetic attachments for easy removal. Reflective logos meet EN20471 standards for visibility, and the entire system folds into a compact three-fold storage configuration.
