Just drink directly from the stream/water source...
...and watching groups of fish swimming at the same time.
What a fun and convenient way to rehydrate ourselves!
Ultralight at its finest! LifeStraw accomplishes the same thing as other filters, but does it at just a tenth of the weight. At only 2 oz (56.699g), it's the lightest way of filtering water while on the go.
Without a doubt, this would be a great piece of ultralight gear to be included in my ultralight bikepacking setup. Just imagine how 'less' water i need to carry and how much weight will be saved with just a LifeStraw attached to the bottle cage.
