Osprey's Duro Handheld Soft Flask Holder provides a high-performance hand-held hydration solution to any active outdoor user.
The Duro Handheld is designed to provide hand-held hydration whilst leaving your fingers free to adjust your jacket or open an energy gel. Duro Handheld contains an interchangeable 250ml soft flask with sports cap for fast flow. It's easy to use, ambidextrous and comfortable, featuring a zipped stash pocket that's ideal for storing keys and a little cash or a bank card.
The zip pull doubles as an emergency whistle, while the contact mesh lining allows it to be comfortable and breathable against the skin. It can be worn in the palm or on the back of the hand, allowing it to be used along with trekking poles.
