Enjoy all the benefits of a flask with none of the drawbacks associated with a lesser flask. Vargo's Titanium Funnel Flask features an integrated silicon funnel that flips up when you're filling up and folds down for sipping. The titanium lid and body allow you to enjoy your drink without any distracting odors or tastes. It has an 8 fluid ounce (240 mL) capacity, measures 5.9" x 3.7" and weighs just 3.7 ounces.
