I work outdoors for 9
[This review was collected as part of a promotion.] I work outdoors for 9 hours a day ( frequently in full sunlight ) and this hydration pack has been extremely helpful! I work away from a reliable source of water quite often and this usually lasts me most of the day without having to refill. It keeps the water cold for good few hours even when in direct sunlight and even longer when you add some ice cubes to it. It's super comfortable and super lightweight.
