Coolflask 128 oz Gallon Water Bottle Insulated with Straw & 3 Leakproof Lid

I’ve gone through a lot of water bottles over the years, and this one honestly surprised me. The 64 oz size is perfect because I’m not constantly refilling it throughout the day. I use it at work, in the gym, and when I’m out running errands, and it keeps my water cold for way longer than I expected. The straw lid is convenient, and I like that it comes with multiple lid options depending on what you’re doing. The carrying sleeve is actually useful too—not one of those accessories that just gets thrown in a drawer. The extra pockets are nice for keys, earbuds, or small items. The bottle is definitely large, so if you’re looking for something compact that fits every cup holder, this isn’t it. But if your goal is staying hydrated without refilling every few hours, it’s worth it. Build quality feels solid, the finish looks good, and it doesn’t feel cheap. So far, no leaks and no complaints. If you’re serious about drinking more water, this is a good buy.

Really happy with this water bottle. The half-gallon size is great for keeping me hydrated throughout the day without constantly refilling it. I love having three different leakproof lids, especially the straw lid for drinking on the go. It keeps drinks nicely chilled and feels sturdy without being too awkward to carry. A practical bottle for the gym, work or days out.

First thing's first: I think this bottle is great. What I'm saying here is generally not a criticism. The material is listed as Stainless Steel. It takes some digging to find that it's 18/8, which means it's an alloy with 18% chromium and 8% nickel. I didn't realize this, and after using the bottle for a couple of days I had developed a really nasty cough that is still with me (greatly diminished) over a week later. Now to the rest of it. The straw lid is not fully leakproof, but it is very resistant to leak and doesn't leak quickly. The other two lids I had no issue with. All that really means is if you're gonna store the bottle sideways, don't use the straw lid. The insulation is very impressive. It was still cold after 48 hours after the bottle sat in room temperature, and after several hours sitting in an unshaded car on the hottest day of the year so far (118F heat index). Probably the biggest thing to keep in mind before purchasing is the handle. Mine hasn't broken, but many others are saying theirs has, and I can tell it's fragile. It's very nice that it comes with a straw cleaning brush, and the bottle sling is nice though the pocket doesn't really hold a phone unless you're willing to really cram it in (and I have to assume doing that a few times will cause the stitching to break). The strap is okay.

I am so pleased and impressed with this water bottle! I had originally purchased it to keep in my car kit for emergency breakdowns in the hot Texas summers, but I ended up loving it so much that I now carry it everywhere. The bottle is high quality and comes with a variety of different lids. I’m currently using the lid that has a threaded cap and carry ring. The cap is threaded on the inside, which is genius, because the threads stay cleaner and you never have to “search” for them when screwing on the cap (great for fumbling fingers in the middle of the night). The cap screws on tight. Other lids have options for straws or “wide mouth” storage. The carry case serves different purposes. As a coozy, it further insulates the bottle. Because it’s fabric, it keeps the large bottle from loudly clunking when setting it down and also protects from dings and scratches. The strap is a lifesaver on this half-gallon version, and I love that the pouch has multiple pockets! I’ve used them at work for pens, mints, etc. The bottle size is incredible - basically one fill in the morning lasts me most the day. I love a well-designed product and this delivers on every count. I’m already thinking about purchasing a few more for camping and travel. I’ve owned TONS of water bottles over the years, and this is easily my favorite. Not even close.

⭐⭐⭐⭐☆ I really like this water bottle overall. The turquoise color is beautiful, and it keeps my water cold for a long time just like it promises. I also appreciate that it comes with multiple lids, so I can switch them depending on what I'm doing. The only reason I'm giving it 4 stars instead of 5 is because it's a little heavy, especially once it's filled with water. That's probably the tradeoff for good insulation, but it's still something to be aware of if you carry it around a lot. Other than the weight, I have no complaints. It's well made, looks great, and has become my everyday water bottle.

In love with it so far, perfect for my carry-on drink refill container. Keeps ice for over 24hrs. Perfect for my long delivery shifts, cuts stop times more than in half- gotta only stop once throughout the day. Appearance is sleak and vibrant defined coloring. Easy to use and grip. Easy to clean and leak proof from my use so far.

I really like this water bottle. The protective sleeve fits nicely, and the adjustable shoulder strap makes it very convenient to carry while walking, exercising, or traveling. I also love that it comes with different lid options, making it easy to choose the one that works best for me. It feels sturdy, practical, and easy to use. Very happy with my purchase!

It is awesome!! Keeps water cold...still cool after 2 days! The size is large but great for my use. The over-head/shoulder strap is a terrific plus for me as I walk with a walker and need my hands free. My first outing was our July 4th street party. Had COLD water all afternoon & evening! 🎇🎆

La llevo usando meses para llevarme el té al trabajo y no quería escribirla antes de tiempo. Los puntos positivos son: -Guarda por mi hoy tiempo el calor, de hecho para que os hagáis una idea, me hago el té por la noche anterior, después de un rato abierto lo meto a la nevera y sigue estando caliente al siguiente día. - Se me ha caído un par de veces y solo se ha deformado un pelín por fuera, no se le ha ido el color ni se ha deformado por dentro. - La funda que trae es más que útil para llevar tu bebida enganchada a la mochila o prenda de vestir (no trae mosquetón ni nada parecido para engancharla). Y si acaso como punto negativo solo puedo decir dos cosas: - Algunas partes son complicadas de limpiar, como los resquicios de la boquilla. - La parte de tela donde está la pieza metálica que trae la funda donde enganchas el mosquetón no parece estar reforzada y la funda acaba girando en algunas ocasiones sobre sí misma. A pesar de esto me parece un gran producto. Dato adicional: tened cuidado que al ser un termo es bastante más grande de lo que podéis pensar.

🧊 Excellente bouteille isotherme, grande capacité et polyvalente La bouteille Coolflask 2L est idéale pour rester bien hydraté toute la journée. L’isolation sous vide est très efficace : elle garde l’eau fraîche pendant des heures, même en pleine chaleur. Les 3 couvercles interchangeables sont très pratiques selon l’usage (sport, bureau, voyage). La paille intégrée est un vrai plus pour boire facilement sans renverser. Le design “gomme à bulles” est original et agréable en main. L’inox est solide, la bouteille ne fuit pas. Très bon produit, je recommande. ⸻ 💧 Solide, pratique et bien pensée Grande contenance, parfaite pour une journée de travail, de sport ou une randonnée. L’eau reste bien fraîche, même après plusieurs heures. La qualité de fabrication est au rendez-vous : l’acier inoxydable est robuste, et les bouchons ferment parfaitement. Mention spéciale pour les 3 types de couvercles fournis – un vrai plus selon les situations. Design moderne et coloris “gomme à bulles” très sympa. Je suis entièrement satisfait(e). ⸻ ⭐ Hydratation optimale au quotidien Très bonne bouteille isotherme : grande capacité de 2L, excellente isolation thermique, et aucun souci d’étanchéité. La paille est pratique pour boire sans incliner la bouteille, et les différents couvercles sont très utiles. Facile à nettoyer, agréable à transporter. Le revêtement extérieur est esthétique et antidérapant. Rien à redire, je recommande sans hésitation.

Bad quality control on the products. Would not recommend buying. One of the bottle caps came without its sealing gasket ring. This made the bottle leak. Coolflask customer service could neither ship me a gasket ring, nor a replacement cap. After several weeks of email exchanges with honestly what felt like a chatbot instead of a human, I was offered a partial refund which wouldn't even cover the cost of ordering gasket rings myself. I'm fed up with the mental hassle of dealing with this company.
