Pure titanium material in body and lid with integrated silicone funnel. Simply flip it up for easy filling, then fold it down to sip comfortably. The flask is very easy to fill and empty and no extra funnel is necessary. Material won’t impart or alter taste, odor or chemicals – meaning you and your single malt stay pure. The funnel also functions as a perfect spout to pour your alcohol back into its original container and the Hip-Flask is completely biocompatible. Easy to Use, nothing to loose and also great as a gift.
