Reusable water bottles might be great for the environment, but they can be hefty and take up a lot of real estate in your backpack or bag. If you work in an office, you’ve probably stared down your bottle trying to decide if it’s worth lugging all the way home for a weekend. These bottles don’t exactly fit neatly in your shoulder bag. Never mind a small crossbody. That’d be impossible. There’s a new type of reusable water bottles that are total game changers, though.

Collapsible water bottles are what they sound like. They’re bottles that either fold up or collapse into themselves, making it easy for you to put the empty bottle in a bag. Made for on-the-go and the modern world of minimalist design, the bottles are made for outdoor excursions, travel and commuting. It won’t be a big deal to take water to the gym now. These cool bottles are made out of BPA-free silicone materials. They’re safe to drink out of, and they come in fun colors. Plus, the bottles are all flexible and shatter-proof. Check out our picks for the best collapsible water bottles for you.
