Hear it from them
"These squash down very small when empty and stay leak-free (so far) when full. They're really useful for traveling by air, as they take up very little space and you can fill them up after security. I haven't tried them in the running belt yet, but the main material is very soft so I'm sure they will be quite comfortable for that."
"Collapsible water bottle. These are great you get 2 bottles they are quite sturdy when full of water and easily collapsible empty. Great for carrying on long hikes etc so you have plenty of water."
"They are specially designed to fit perfectly into the pockets of vests and hydration belts.
I found the reliability to be excellent: the silicone valve allows easy water flow (just bite lightly) and they are guaranteed to be leak-free. In addition, they are BPA and PVC free, for a pure taste of water. Receiving two bottles is ideal for long outings."
