Bring a bottle anywhere with the Space Shaker Collapsible Travel Bottle. This device easily collapses, allowing you to enjoy your protein shake or infused water wherever you go. Thanks to its space-efficient design, Space Shaker fits in small bags and spaces so you can carry more. Designed for your hand, every part of the bottle is easy to hold. Likewise, its bellows surround your fingers to provide an ideal grip. The bellows also help break powder clumps in your protein. Additionally, the click-on mixer attached underneath the lid helps make your drink smooth. The mixer attachment also doubles as an infuser. To use Space Shaker, remove the lid, put your protein powder inside and close the lid for safe traveling. Whenever you want to drink it, open the lid for the bottle to expand and fill it with water. Close the lid and shake it before drinking.
