The only bottle I use is a bottle of scotch at the end of a great day. You, you might use a bottle to carry your workout beverage. That’s fine too. The Mous Shaker bottle is running a Kickstarter campaign to fund their modular designed and incredible smart shaker bottle. The bottle features a rounded bottom with a squared legs designed which means that shaking has no corners to get stuck in. Cleaning is also quite easy as there are no heavy threads, again no corners, and a modular design which allows each piece to come apart. Clever design!
