I find ESS V12's work pretty well since the side vents are pretty unobstructed. But I recommend Fogtech. I have been using it in wet wipe form and its keeping my goggles defogged for an 8 hr day.
The wet wipe is alittle of a waste since you have to keep the solution from evaporating off the wipe after you open the package. I believe there's a spray bottle version of it.
Otherwise, DIY a fan to put on your vest using computer fans. Works like a charm
