MyiaurPolarized Sunglasses for Men Anti-Glare 100% UV Protection Classic Sun Glasses for Fishing/Driving/Golf

Can you tell me that what are the specific weight and volume of the sunglasses?

Do these slip while running?

Does the silver block the sun well... I need dark lenses because i have sensitive eyes?

First time i ordered this sunglasses it came with a pouch, and the second one i ordered did not. how do i contact the seller?
