Never underestimate the enjoyability of a good stiff drink. And never go without one either, so long as you have this superb liquor vessel on your person. Crafted from solid titanium, it's food-safe but still tough enough to weather any adventure. And the integrated silicon funnel design promises both easy filling and ensures that you don't have any extra pieces to carry around and potentially lose. It can store up to 8 ounces of your beverage of choice and, should you get a few as groomsmen's gifts, they can be engraved by most jewelers and/or engravers.
