Hydrapak Flux+ 1.5L Bottle

A soft flask that filters what you pour into it. The filter is factory-installed, so there is nothing to assemble or buy extra in order to drink.

The filter

Rated to treat 1,500 liters, at a flow rate of one liter per minute. Enough to cover a hiking season without a second thought, by drinking directly from the flask.

One wall, two layers

The body is made of thermoplastic polyurethane with a double-layer laminated film, with POM and silicone for the hard parts. It is flexible and rolls up when empty; the double layer gives it an elasticity that a single wall lacks.

Capacity 1,500 ml, weight 143 g.

The mouthpiece stays clean

A polyoxymethylene dust cap with silicone seals closes the drinking spout: no leaks in your bag, and no dirt on the part that goes to your mouth. It's the detail most often missing on this type of flask.

Carrying it

Ring handle, for carrying by hand, on a finger, or clipped to a backpack strap.

For an outing where water can be found along the way, it replaces both your water bottle and a filter straw.
