Frequently Asked Questions

Does the bite valve have a shut off feature?

Yes, the shut-off valve on the Blaster Bite Valve is helpful for transporting the reservoir when it’s not in use. This secondary shut-off is useful for carrying a reservoir before or after an activity to avoid water flowing from the reservoir. To activate, twist the blue portion of your Blaster Valve.
