Its all in the pre Prepand caring for them when you out riding .. , I am super OCD with Goggles, have one of those clear Plastic lock down boxes form the pound shop , all in lied up , with clean rags..
I used only two pairs on each day at the Natterjack, and it was Humid , sandy , with light Drizzle I always use Double glazed lens ( Scott Hustle )... Once a drop of rain goes inside you F*****, try not to keep taking them on and off , as you you head temp will be differnet to out side temp and they will steam up then . and if you do take them off put them on to of Grip, FACE UP ! so no water get on them , I stick some cleam dry strips of rag up my race shirt sleeve , and gently wipe the lens clean at Each check, also pat the foam dry to take up any sweat..
Dont stick them on back of Helmet or they will soak up and the Mud and Shit, Ive got a New set of Rolls Off , but Never used the as the Double lens thing has always worked for me ..:burnout:
