Say no to landfills with the Narrow Mouth Tritan Sustain Water Bottle from Nalgene. This bottle is from the Sustain line and the US-based brand has cleverly used 50% plastic waste to make it - that's like giving 8 plastic bottles a new lease of life. It’s still as adventure-ready as all the other bottles. Plus, it's got a leak-proof screw top and it's lightweight, so you can just toss it in your pack and go.
