Use

Choose the correct adapter for your water bottle. The short tube has an integrated adapter for the normal PET bottle (28 mm). The set comes with three additional adapters:

• Evian-PET (24 mm)
• Sigg (42 mm)
• Nalgene (63 mm)

Adjust the straw to a correct length, so it will reach the bottom of your water bottle. Screw the adapter on your bottle, connect the drinking tube to the adapter short tube, and you are set.

In addition to the adapters, the Source Military Convertube has a Source drinking tube with a high-flow Storm drinking valve. The tube and adapters come in coyote brown.
