Best for outdoors man: Toaks lightweight flask

When you leave whiskey or scotch in a stainless steel flask for too long, it imparts a steely task to the spirits. It's got sort of a grey color like titanium often does, but it also has a small plastic washer in the cap, like soda bottles do. It is light, perfect for outdoor backpacking. It is corrosion-resistant, and absent of metallic taste or odor. If you're thinking your booze is all pure, it's got a plastic surface for the nit pickers. It will pretty much never open accidentally, but it does take about 8 full twists to open. It is easy to carry, both in the pack and in a pants pocket.

You can keep your drink in titanium much longer than stainless
Very high quality toaks titanium flask
