A Nalgene is a proven, bombproof bottle, and it's the hub of a whole ecosystem of gear. Cana Provisions carries authentic Nalgenes and everything that works with them. Start with the bottle: classic Nalgenes and our exclusive Water Data Card bottles, printed directly with treatment doses, sterilization steps, a freeze line, and conversions, in 16oz wide-mouth, 32oz narrow-mouth, 32oz wide-mouth, and 48oz wide-mouth. Then build it out — replacement caps and lids, and cap retainer tethers, plus filters and adapters that fit Nalgene threads, like Steripen UV pre-filters and gravity-filter bottle adapters, so your bottle does more than hold water. Authentic, dishwasher-safe, impact-resistant, and made in the USA: the bottle, the filtration, and the accessories, all in one place.
