The Nalgene water bottle with sophisticated closure technology. One-handed snap closure for quick and comfortable drinking during your outdoor activities. The lid can also be closed to 100% waterproof. By unscrewing the complete cap, the bottle can be quickly refilled and cleaned perfectly. Made of 50% Tritan (TM) polyester, the lid is polypropylene. Dishwasher safe. Super handy, the 0.65 litre variant fits in standard drink holders, even on the bike. As usual with Nalgene with level indicator p. B. for safe mixing of mineral drinks.
