If the idea of carrying a flask is supposed to provide you with a drink while keeping things on the down low, than this Binoculars Flask will be perfect for taking that little nip while bird watching.
Each side of this flask holds 8 oz of your favorite drink. You could have one drink on one side and another on the other side. Each flask also comes with a handy funnel to make filling it super easy.
It also comes with a wrist strap to make it look even more authentic. It will cost you $11.95 from Baron Bob. It makes a great gift as well.
