Solstrale, meaning “ray of sun light” in Swedish, stems back to Grundens' roots and commitment to protecting anglers from the various harsh conditions they experience on the water. The sun is no exception. This entire collection is UPF50 rated to prevent sunburn and long-term skin damage caused from harmful UVA and UVB rays that are often unavoidable. But sun protection only works if you’re comfortable enough to wear it, and this collection offers a suite of HeiQ™ technologies including anti-odor, stain release, and thermo-regulating properties to keep you cool, comfortable, and ultimately focused on the task at hand.
