When you think about things that you need to spend any amount of time in the wilderness, a flashlight with multiple beam settings and a compass are considered essential. While we’re not going to say that a flask, shotglasses and a bottle opener are essential, they can definitely help the experience. But none of that really matters when it comes to the VSSL Flask because it contains everything we’ve just talked about. Each 9″ long, 2″ diameter Flask weighs 18oz and contains a dual mode LED “flood” beam lantern light, two collapsible stainless steel shot cups, bottle opener, compass and a 10oz flask (which is lined with an atom thin layer of glass to prevent your booze from tasting “tinny”). It is, quite literally, brilliant.
