KCHAWAVwrote a review of Zeal Detonator Spherical Polarized Photochromatic Goggles on February 11, 2009
Wow! Used this goggle a few times in classic SoCal clear sunshine and they were great. True test this weekend in VERY challenging conditions: partial sun but mostly cloudy with some intermittent dark clouds, light to moderate snow falling, extremely flat light most of the time. The Zeal goggles performed FLAWLESSLY in all conditions! Lens shading changed with the light and I could see bumps and detail in the snow that no one else could, even during the worst lighting. Only thing they couldn't do was help me see through the fog that rolled in later in the afternoon, which no goggle can do!
