The Ultra Handheld Chill Bottle from Camel Bak is a 500ml, insulated, collapsible flask that moulds to your hand & keeps your water cold twice as long as a normal bottle, but without the extra bulk & it’s so light & comfortable that you’ll almost forget you’re carrying it. It is surrounded by a 3D Ventilated lightweight mesh which offers multi-directional air flow & cushioning to maximise comfort & breathability for your hand when carrying. The secure elastic strap system lets you customise your hold so you don't drop it even if you relax your grip. It features a secure zipped pocket for quick access & storage for the important bits you need such as keys, phone or cards so you don't need to bring a bag on a run or a long walk. There is also a small stretch pocket to store extra fuel for those particularly long runs. It is highly reflective which will help increase your visibility on early morning or evening runs.
