a peak stops rain goin onto ur lense.. perhaps if its raining straight down. bit of wind and a peak dunt stop nuffin.
i dont give a **** bout some 'pro' players who wear peaks. i play my game and let others get on with theres.
i dont like peaks. never have and never will. much rather wear a beany with a peak on it and tape up the air vents in the top to stop water running down.
