LINDOFlex/Stretch Band Pro Back Style Hat - The Great Outdoors

Why is the elastic band only attached at the bottom? This causes it to flip out of the hat often. It's extremely annoying

I only see one size available. Does the seller offer l/xl and color options for this style hat?

Is this a flatbill? Do they offer a baseball cap style bill with this logo?

Is this a true flex fit or a snap back?
