A good flask doesn't need to be flashy. It just needs to hold booze, without leaks, comfortably, and hopefully last for a long time. The Stanley Master Series Hip Flask checks all these boxes. It's made from rust-proof, BPA-free 18/8 stainless steel, with a contoured back for a comfortable fit against the body and a wide mouth opening for easy fill-ups. Finished off with a hinge-connected cap that's impossible to lose.
