  • My “all-day” hydration companion.
Style: Straw - 22 Oz Color: Fire Red
I recently purchased the 22 Oz IRON FLASK Sports Water Bottle in Fire Red, and I couldn’t be happier. The double wall insulation is incredible. It keeps my drinks nice and cold. Whether I’m at the gym, taking a stroll through the park, or just running errands my beverage stays at the perfect temperature. The three included lids are great. The Carabiner Straw Lid with two straws is perfect for sipping on the go. The Flip Lid, which is my personal favorite, is convenient for quick access. Lastly, the Stainless-Steel Lid adds a touch of elegance. Plus, they’re all 100% leak-proof! The 18/8 stainless steel construction ensures that my water never tastes metallic. It’s also BPA-free and non-toxic. I love the peace of mind knowing that my water bottle is safe and durable. I can’t leave out the fact that that I no longer have to deal with annoying condensation. The Iron Flask remains sweat-free, even during intense workouts. Plus, the Fire Red color is vibrant and eye-catching. Overall, the 22 Oz IRON FLASK Sports Water Bottle has become my constant companion. It fits perfectly in a cup holder, and I love the versatility of the different lids. If you’re looking for a high-quality, stylish water bottle, look no further. ... show more

  • Durable and easy to clean
Style: Straw - 22 Oz Color: Blue Waves
Love my iron flask water bottle. It came with three different lids that you can change out, along with extra straws and cleaning brushes. I picked this size because it still fits in the car drink holder (and in backpack water bottle holders), but also has a wide enough mouth for easy cleaning. Haven't had any issues with leaking, and the bottle has held up well (I've banged it around a bit at the gym and transporting in the car). I typically use it for cold water (with ice cubes added), and water stays cold for a pretty long time; haven't tried it with anything warm though. I've bought a few bottles from this company - worth it! ... show more

  • I've had this product for almost 2 years or so and it's great!
Style: Straw - 40 Oz Color: Rose
I haven't really dropped it, only once or twice and as you can see in the pics the dents are minimal. It keeps my water cool/cold throughout the day and even through the night, it all depends when I fill it up. I got the 40z which can be rather heavy so I'd suggest buying one of those attachable handles if you'll be walking around with it alot. The covers it came with is great. I had to buy one of those straw and bottle cleaners to properly wash the straw and it's associated cover but all-in-all it's a great product. Ironflask is truly great, I'm able to get great quality and cute products with breaking my bank. ... show more
