Use water at temperatures between -4degF/-20degC and +104degF/40degC. Do not use: alcohol, fatty products (dairy, oils, etc).In temperatures below 32degF/0degC, blow into the pipette after use to flush out the water and reduce the risk of freezing in the pipette and mouthpiece. If the sound of the water in your bag bothers you, simply empty the air contained in your water pouch by turning it and then directing the air bubbles to the tube while suctioning them. | Forclaz Mt500 2L Water Bladder in Blue
