The Osprey NATO 58 Pattern Water Bottle and Mug is a classic piece of outdoor equipment and is standard issue to the British Armed Forces. The bottle holds 1 litre of water and is made of a rigid black plastic that will not split or break. The mug holds 500ml and sits neatly on top of of the bottle.
This heavy duty water bottle features a seal in the lid to prevent leakage, while the lid is permanently attached to save you losing it. Typically the mug sits in the bottom of a canteen/utility pouch and the bottle is dropped into it (upside down) for quick access. When purifying collected water with chemicals, the BPA free, black plastic of the Osprey Water Bottle prevents light from affecting the purification process, making this a safer choice.
