When it comes to being active and on the go, staying hydrated is a must. Whether you're going for a walk, running errands or keeping up with your kids, grabbing a water bottle on your way out is one way to ensure you're staying on top of your health. Take Brazilian fashion model Gisele Bündchen, for instance. She's known for her beauty, but also for her affinity for keeping up with her fluid intake! The star has been spotted carrying the Owala stainless steel tumbler, which is perfect for keeping drinks cold or hot for hours - and surprisingly, it's currently 20% off as part of Amazon's Cyber Monday Sale. Made of BPA and phthalate-free steel material, this cup-holder-friendly pick has double insulation for temperature control, is splash-resistant and is dishwasher safe. It even comes with a removable, reusable straw. See it! Get the Owala Stainless Steel Triple Layer Insulated Travel Tumbler for $24 (originally $30) at Amazon!

However, the star of her look - for Us, at least - was her bright Owala water bottle. Simple and durable, this pick can handle any drink and comes in 10 color options as well as two different sizes (although the 24 oz is the one that's discounted today). And while the sleek appearance and celebrity approval check two major boxes for us, this tumbler also has over 5,000 five-star reviews, which really seals the deal. Jennifer Aniston's Personal Trainer Loves This Sleek Water Bottle While reviewing and gushing over this water bottle, one Amazon reviewer said, "It keeps ice cold for hours and holds just the right amount of water to keep me hydrated without constantly needing to refill. Easy to use with or without a straw and fits in my cup holder." "It's a great tumbler," another person noted, "It doesn't leak, has a good straw, is easy to clean, and keeps things cold all day. I really like it." For many, keeping your drinks cold or hot is essential - especially when you're super busy. If you need a new tumbler to replace your tried and true option, this Bundchen-approved alternative could do the trick! See it!
