    I absolutely love this cup! It’s my gym cup and it keeps my water cold for over 12 hours!

    That's amazing, Allyson! We're so glad you love your new Siren Bottle :)

    Best Water Bottle

    I love using straws and feel so wasteful whenever I have to use a paper/plastic one. I also love really big water bottles but dislike that most of them don’t come with a straw or have to tip over to use the spout. This has been my game changer!! No wasteful straws and Nor more having to tip a heavy bottle over to get a drink! Absolutely love this bottle and can’t wait to buy more!
