I've been absolutely loving the ESS V12 Advancers in the colder weather. Been wearing them to every game since fall, basically since the temperatures dropped.
I noticed a HUGE difference in fogging/condensation performance when I switched to applying Fogtech with a very high quality microfiber cloth that came with my wife's fancy-pants high-fashion glasses.
Back in july/august, they would always condense up to the point where I had to switch to my JT Thermals (these should be in
everyone's standby eye-pro collection). But they're excellent in anything ~15-18C and below.
edit: for the mask you see here I use a standard metal mesh face mask that I've painted "multicam"
