• Lightweight and durable, pack it anywhere for your backup hydration, emergency, or on-the-go needs
• Unlimited shelf life means no need to worry about how long it’s been in your emergency go-bag unused
• Highly versatile: Can also be attached to most water bottles and to standard gravity hoses with removable threaded bottom cap
• Long-lasting membrane microfilter will last up to 4,000 L (1,000 gallons) of water, that’s enough drinking water for one for over 5 years
