The durable and leak-proof construction is worth noting. I've had no issues with leaks or spills, even when the bottle is fully extended and stored in various positions. The silicone material is easy to clean and has proven to be robust enough to withstand the rigors of travel.
It is foldable which is very convenient to carry on the go. The bottle is high capacity which is nice.
The capacity is so large that it basically holds enough water for a whole day at a time, making it perfect to take with you when you're on the go. And it is foldable, folded up in the bag does not take up space.
It's my must-have water bottle for outdoor hiking, climbing, and biking! Great capacity and awesome water storage!
