Camelback Ultra Handheld Chill Stow Flask

This handheld features the first insulated soft flask on the market—and it’s so light and comfortable. The 500 ml insulated soft flask keeps your water cold twice as long as a normal bottle, but without the extra bulk. The soft, collapsible flask molds to your hand, and the stretchy elastic straps keep it secure even when your grip is relaxed. The flask is surrounded by lightweight mesh and features a secure zipped pocket for your phone, card or keys.
