Simple Modern Water Bottle with Straw lid | Insulated Stainless Steel Thermos | Reusable Travel Water Bottles for Gym & Sports | Leak Proof & BPA Free | 24oz, Buttercup

I’ve been using the Simple Modern 24oz Mesa Water Bottle for about two weeks now, and I honestly couldn’t be happier with it. As someone who’s constantly on the go — from workouts to errands — this bottle has become my daily companion.Insulation: The double-wall insulation is no joke. I filled it with ice water in the morning, left it in my car during errands (in Las Vegas heat!), and it was still cold over 6 hours later. I haven’t tried it with hot drinks yet, but based on how well it holds the cold, I have no doubt it would perform just as well.Straw Lid Design: I love the built-in straw! It’s leak-proof and easy to sip from while driving or at the gym. I tested it upside down, shook it around — no leaks at all. Perfect for people like me who toss bottles in bags and forget about them.Build Quality: The matte forest green color is beautiful and modern. The bottle itself feels premium — sturdy, not too heavy, and easy to grip even with sweaty hands.Fit: It fits perfectly in standard cup holders, which is a small thing but makes a big difference for usability.⸻Final Thoughts:I’ve tried other insulated bottles before, but this one stands out because of its thoughtful design, effective insulation, and sleek look. I’d highly recommend it to anyone looking for a dependable everyday water bottle that actually lives up to its promises.✅ Durable✅ Leak-proof✅ Keeps drinks cold for hours✅ Fits car cup holders✅ Sleek, modern design

Super cute and vibrant color. Keeps my kids water nice and cold

As a fan of Simple Modern products, I was excited to try their kids' water bottle, and it hasn't disappointed. This bottle is perfect for keeping my child's drinks cold all day long, even in warm weather. We've been amazed to find ice still floating around after a full day at summer camp!The leak-proof straw lid is a lifesaver. It's designed specifically for this bottle and forms a tight seal, so I don't have to worry about spills in my bag or car. Plus, the bottle comes with two straws – one fitted for the lid and another standard one, offering flexibility.My child loves the simple design of the bottle, and the sturdy handle makes it easy for little hands to carry. It's also the perfect size for most cup holders.As a parent, I appreciate that the bottle is BPA-free and dishwasher safe. It's a durable and high-quality product that I feel good about my child using every day.If you're looking for a reliable, well-insulated, and kid-friendly water bottle, I highly recommend the Simple Modern Kids Water Bottle. It's been a fantastic addition to our family's daily routine.

Everything by Simple Modern has exceeded my expectations. I needed a lightweight water bottle that would keep my water cold. This is a great quality cup! It’s comfortable to hold, as I am a cancer patient, very easy to clean, drink from, and super cute design with my stickers! Will sometimes shoot a bit of water out, but worth it for all the other pros!

Keeps my drinks cold for hours on end. And has stayed in tact even though I drop it regularly. I can store it inside a bag and it won’t leak.

Been a SimpleModern fan since day one. Love the coffee tumblrs, I've bought multiple over the years. Love the company and the brand. Coffee stays hot in the tumblers, water stays cold in the water bottles. An issue I had with the water bottle is that the one I had specifically wasn't rated as leak-proof, and it did leak on it's side or when placed in a bag. Bringing to the beach also gets sand stuck in the straw mechanism/air valve and causes leaks. For these reasons, I recently tried out a Hydroflask water bottle (also good, keeps very cold, but then I lost it) and Yeti (20% more expensive and did not keep cold very well, but also was a slightly different shape so that might have something to do with it; I ended up returning it). Anyway, came back to this SimpleModern one: in my short time with it, it hasn't leaked (even when on it's side or inverted, though I make sure to not rigorously shake it like some other reviews mention). The *only* minor complaint is that the air valve is quite tight: it pulls a vacuum at the beginning of the sip, and then makes an annoying suction noise after a second or two. The valve is quite tight to prevent leaks but for that reason you have to pull a little harder suction when you sip. Every time I sip it makes the noise. The Hydroflask mechanism for preventing leaks was better (but I also believe patent-protected, so not sure if we'll see it on a SimpleModern). Again, this is just a minor annoyance, it's not perfect, but it's good enough. I still recommend the water bottle, I like the company and will continue to buy their products.

The “Mesa” model does NOT keep water cold at all. Such a bummer because I love my Simple Modern “Summit” bottles and have had a few for years. Wanted to try this slim design but it was a fail. May as well be a plastic bottle. I ordered a new Summit and compared them side by side and the Summit kept water cold overnight easily, even with a straw life. I returned the Mesa and will be sticking with the Summit. Unfortunately the descriptions are confusing - “double wall insulated” vs “vacuum insulated” but just know the Summit is superior. I reached out to Simple Modern and their customer service did reply right away so I’m still a fan of the company, just not this model.
