If you can 'afford it,' nothing beats 'Gortex' and a baseball type hat to keep the hood off/above your face (add 'spectacles' to that
) But light/water proof (whom ever makes it) is key.
Most of these types of products are 'breathable,' but are one hell of a good wind-breaker .... which means they will be darned warm regardless of the weather. A good thing in the winter, not necessarily a good thing in warm weather. There, light
clothing that will move 'sweat' (cottons not one of them) away from your body is a 'best practice.'
Just thoughts as it's supposed to hit close to 100 degrees here in Southern Oregon, and I have to tweak the yard sprinkler system.
Ah hell, just strip off your cloths and put on swimming trunks .. you're going to get wet as heck no matter how you do this .. if you're going to fine tune the Bloody things.
Just kidding, but the swim suit really is the way to go.
