You're plastic. Cold, shiny, hard plastic.

Check out these rad Nalgene flasks. Each flask holds up to 12 oz, comes with an insulation sleeve, and even features a 1 oz cap, which is coincidentally the same amount in a small shot of alcohol. Who's gonna care about bisphenol-A when they're getting their drank on with their oh-so-fab Nalgene flasks. Yay Nalgene junkies!!
