Up until recently I would sweat like a paedophile in Mothercare just standing still. The only goggles I found that work reliably are either ESS V12s or ESS Profile Turbofans.
Funny that coz my team mate brought the ESS turbo fan goggles and hated them but i have heard good things about them. I have only worn the Trackers once and had great results but i guess you need a good 6 battles in something to really know how it holds up
