The Columbia Men's PFG Solar Stream II Hoodie is engineered for performance in warm to hot environments. Omni-Shade Broad Spectrum UPF 50 technology helps protect covered areas by blocking a wider range of harmful UVA and UVB rays. The Skin Cancer Foundation recommends this fabric as an effective UV protectant for covered areas only. Omni-Freeze technology enhances cooling comfort through accelerated wicking during active wear. Omni-Wick performance fabric moves moisture to the surface for rapid evaporation. A cross-over hood provides added neck coverage when exposed to the sun.
