I hate carrying things in my hands, so this is so handy for going on walks/hikes where I don't want to be loaded down with a big or extra stuff. I just drink and collapse it. So handy for music festivals and events to not have to buy water for $6 too.

The size is so perfect very weightless. My toddler loves this and she is always excited to use her portable water bottle.

Quality is actually really great. Holds liquid well, even if you close the cap and tip it upside down with coffee in it (what my wife uses it for) it doesn’t leak. Collapsed and expanded easily. I’m a happy customer!
