Drink to shrink.
Ready for adventure, the collapsible Hydrapak Softflask 500ml Water Bottle is particularly convenient for climbers, hikers, and backpackers. It shrinks as you drink until it's the size of a stack of papers that fit in the palm of your hand. That means you can store it in your backpack regardless of how much gear you have in there. Its wide screw cap is easy to fill, and the twist lock ensures that it won't leak. The soft silicone bite valve is easy to drink out of when you're on the move.
