The Nalgene Wide Mouth Flexible Water Cantene is a camping classic and essential. The multi-layer material offers durable strength and remains soft and flexible so it can be rolled when empty. The wide mouth opening makes it easy to add ice cubes or powdered drink mixes without spilling. The gusseted bottom allows the canteen to stand upright. This cantene can withstand both freezing and boiling temperatures from -20 degrees F to 220 degrees F. The loop-top retainer prevents the cap from getting lost. Made in USA. Available in 32 oz., 48 oz., or 96 oz. Collapse the container for easy storage when finished. BPA, BPS and Phthalate Free.
