SEATTLE — The Seattle Mariners might just be giving away the best man-cave accessory ever created.

On April 24 against the Minnesota Twins, the Mariners and the Emerald Queen Casino are hosting a special ticket offer for an event called “Guys Night Out.” Male attendees on that day over the age of 21 will get a free drink and a Mariners beer hat.

What is a beer hat, exactly? Well it’s a Mariners cap with a built-in bottle opener.
