Looking for a lightweight and packable alternative to plastic or aluminum bottles? These tear-resistant, PCV- and PBA-free water sacks come in three sizes: 2, 4, and 10 liters. Carry drinking water, use as an outdoor shower or even a camping pillow, or fill with sand and make yourself a WWIII bunker.

Features

The food-grade coating on the inside ensures that you can safely drink water from these. The bag can be fixed to the backpack, and it is made from tear-resistant fabric. The 4- and 10-liter versions can also be easily fixed to branches or vehicles thanks to the two buckled handles.

• Standard 63 mm wide-mouth cap, compatible with e.g. Nalgene)
• Drinking valve with a dust protection cap
• Flow adjusting valve
• Easy cleaning and fast drying due to the large 52 mm opening

Use

The cap is the same 63 mm wide-mouth size as e.g. on Nalgene bottles. So, anything that goes on Nalgene, goes on this, too.

Therefore, you can combine these with e.g. the Katadyn Vario microfilter. Or turn the bag into a water reservoir with the Source or Ortlieb drinking tube. 

They also have other uses besides storing drinking water such as a camping shower (Ortlieb sells a separate accessory for this), seat or head pillow, sandbag, and buoyancy means for diving.
