For freshness that can’t be faked, swig no further than the Seeker™ Water Storage Bag 4L by HydraPak.

The leakproof tethered cap works with any separately available 42-millimetre threaded screw-on water filter. Go from the campsite to the crest with a low-profile handle for durability and comfort. Attach, touch, and go, thanks to the dual load-bearing lash points, while a 100% BPA and PVC-free construction of TPU and RF welded seams adds abrasion resistance, elasticity, and durability. Drink it in at the pinnacle thanks to a 42-millimetre opening for easy refilling and a leakproof cap. When it’s time to fold at the finish line, the Seeker™ scrunches to a conveniently compact size for no-fuss storage. From frosted tracks to scorching trails, this bag also works sufficiently from a frozen state to a steamy 60 degrees Celsius.
