Review on 🚰 KOR Nava Filtered Water Bottle - BPA Free, Clear, Reusable, Ribbon Red, 650mL, 22 Oz - Eco-Friendly & Leak Proof - One Click Open w/Handle - Ideal for Everyday Use and Travel - Dishwasher Safe by Jenn Arnold

I love these bottles. I keep leaving them in hotel rooms and then buying a replacement without hesitation. They're perfect for the airport - they have plenty of water but aren't as big as a full 1 liter bottle. Fits in my carry-on water bottle bag (Osprey). Easy to fill. Even London water becomes tasty :-). The only downside is that the bottle closes too tightly. If you fill a bottle on the ground and then open it on the plane for 30,000 feedings, you'll end up with a full water cycle. Due to the drop in pressure, it simply squirts out of the bottle. You can't just take off your hat. Instead, unscrew the entire top slightly to let the air out, then screw it back on.
