Hydrapak Softflask 500

The Hydrapak SoftFlask is exactly what it sounds like – a water bottle that is soft rather than hard. When filled with water, they expand to their full capacity. But when your water is all gone, they collapse down to the size of a crushed beer can. This makes them easy to stow in your pack or pocket instead of taking up a ton of needless room.



The main thing I like and dislike about the SoftFlask is the size. They I like that they are small, which makes them perfect for carrying around in a pocket or in your hand. But I also dislike that they are small, because they don’t carry enough water for me on a typical day-hike/trail run. This supreme mobility, however, makes them so easy to stash into a pack as the soft material conforms around whatever gear you have in there. I’ve been known to keep them in my back pocket, or even in my hand as they are totally unobtrusive. They even have loops so you can hang them from a climbing harness or a pack strap.



Once the water is gone, the flasks collapse on themselves flat as a pancake. They take up zero room, which provides space for more stuff/less weight in your pockets or man satchel.
