Review on 🌊 Tap Multi Function Collapsible Water Bottle - BPA Free, Lightweight & Flexible, 16 oz/500 ml, Orange, Ideal for Sports and Travel by James Rogers

These bottles are very handy. I took it on an overnight camping trip to use as my main water bottle. I carried large bottles in bottle holder pockets and filled them from them. I have one bottle attached to the shoulder strap of my backpack, ready to hand, and the other in the outer back pocket so that I can swap out if necessary. My only complaint is that the lid doesn't always unscrew easily, which allows water to seep around it. So I can't call it hermetic. The lid often seemed to move sideways, so even allowing for user error, that was an exaggeration. Otherwise, it is easy to clean and convenient as it can be rolled up and stored. It's also very light, which is useful when hiking.
