Reflections from anything.  I was shooting my daughter skiing yesterday, the CPL really helps knock down the reflective glare from the sunlit snow.
EOS 1D X, EOS M, and lots of lenses

They also work as a ND filter to lower your exposure and will take the glare off of wet surfaces, which can have the effect of reducing the dynamic range by turning strong highlight areas into weak highlights or light midtones.

In the shot below, taken in horrible mid-day light, I was able to reduce my shutter speed to 1/2000s which gave me more room to adjust exposure for darker horses (where I dialed it up to 1/4000s or higher) and turn the logs from a white reflection into their natural color, restoring detail that would have been blown out without a C-PL.

EOS 1D X, 5DIII, M + EF 24 f/1.4II, 50 f/1.2, 85 f/1.2II, 300 f/2.8 IS II || 16-35 f/4 IS, 24-70 f/2.8II, 70-200 f/2.8II || TS-E 17 f/4, 24 f/3.5II || M 22 f/2, M 11-22 f/4-5.6 IS | 18-55 f/3.5-5.6 IS || 1.4x III, 2x III
I only shoot at ISO 100 with perfect technique - should I get a Nikon?
