If there's one thing we know Gisele Bündchen doesn't skimp on, it's hydration. The supermodel has been spotted carrying this internet-famous water bottle on several occasions - it's known for its minimalist design and built-in straw. Just in time for the holidays, it's now available in limited-edition colors on Amazon - and they're already selling fast. The one Gisele swears by? The Owala FreeSip Insulated Water Bottle. She's been seen carrying it while on the go, proving just how easy it is to tote around thanks to its slim, ergonomic handle and leak-proof lid.
