5oz Stainless Steel Flask - Leak Proof & Portable for Outdoor, Camping, Hiking & Travel

Flasks have that charm of a bygone era, when spies and diplomats made rain and shine. Today, flasks are appreciated for their convenience - they allow you to carry your favorite whiskey wherever you go.

This classic 148 ml (5 oz.) Mirror stainless steel model can hold enough liquid for most situations.
Interesting note, the cap is retained on the top of the flange by an articulated arm. Anyone who has ever lost their keys in a yard of snow, because their fingers were frozen over, will appreciate this engineering effort.

This flask, like any other flask for that matter, is designed to store alcohol for a day or two. Although stainless steel is not a reactive metal, it would eventually gradually alter the taste of the liquid it contains.
