Nalgene narrow mouth bottle, grey, 500 ml (16oz.)

Thanks to the smaller opening of the Narrow Mouth less water can rush out, making it easier to chug mindlessly. Everything else about the Narrow Mouth is like its Wide Mouth compatriot, so you get all the durability and no-leak peace of mind but without the stress of a mess. Just note that no ice cubes or lemon wedges are getting in here, so if you prefer more than water in your water bottle, check out our Wide Mouth bottles. Nalgene narrow mouth water bottle is solid and durable with no bend or flexibility, so it won't get crushed in your pack. Graduation markings on the side help you to keep track of your fluid intake or serve as a useful guideline when mixing up an energy drink in your Nalgene. The convenient loop-top design means you'll never lose the lid. It will fit in your pack side pocket, like all Nalgene products it is guaranteed for life.
