Coolflask 128 oz Gallon Water Bottle Insulated with Straw&3 Lids, Water Jug Large Stainless Steel Metal Vacuum Wide Mouth for Sports, Gym or Office, Non-BPA Keep Cold 48H Hot 24H, Samurai Cyan

Product: Coolflask 128 oz Gallon Water Bottle Used for: 1 month and 3 weeks Key Features: – Large 128 oz capacity for all-day hydration – Durable stainless steel build with solid insulation – Comes with multiple lids for different uses – Carrying sleeve with strap for portability Ratings: Quality: The quality of the bottle itself is excellent. It feels premium, well-built, and the insulation works great. I’ve only used it for cold drinks, but it holds temperature impressively well. My only complaint is the carrying cover—it feels a bit cheap, and the zipper on mine already broke. A higher-quality sleeve and handle would really make this perfect. Rating: 5/5 Performance: Day to day, it’s been great. It holds cold temperatures for a long time, doesn’t leak, and the different lids all function smoothly. The bottle is large but manageable, and everything feels solid in use. Rating: 5/5 Value: It’s not cheap, but for the quality of the bottle itself, it’s worth it. The insulation, design, and durability justify the cost. The carrying case could use improvement, but it doesn’t take away from how good the bottle is overall. Rating: 5/5 Pros: – Excellent insulation and temperature retention – Strong, durable construction – Multiple functional lids – No leaking issues Cons: – Carrying cover feels cheap and zipper broke early – Could use a sturdier handle design Summary: The Coolflask 128 oz Gallon Water Bottle is a fantastic, heavy-duty option for anyone who needs to stay hydrated throughout the day. The insulation is impressive, and the build feels premium and solid. While the carrying cover is a weak spot, the bottle itself more than makes up for it with performance and quality. If you’re serious about your hydration, this is worth the investment. Overall Rating: 5/5 Disclaimer: This review is based on my personal experience using the product.

I’ve had this water bottle for a long time now and use it basically every day. It goes with me to work, the gym, road trips, fishing — pretty much everywhere — and it’s taken plenty of abuse over time. Dropped it multiple times, tossed it around in the truck, and it still works great. What I like most is that it’s simple and reliable. It keeps water cold for a long time, the straw setup is convenient, and the large size makes it easy to stay hydrated throughout the day without constant refills. I did end up breaking one of the straps eventually, but honestly considering how much use this thing has seen, I can’t really complain. The bottle itself has held up way better than I expected. The only downside is that you need to make sure you clean out the straw if you’re mixing an electrolytes or other mixes you definitely will need to clean the straw down as it can have some buildup. you can see from my pictures just how much I use this product to the point where I actually broke the threading on the cover. Definitely one of those purchases where I feel like I got my money’s worth. Easy 5 stars from me.

I've tried various insulated coolers in various sizes. This Coolflask 64 oz is perfect for my needs be it exercising, yard work, or just next to my desk. The Coolflask has no problems keeping ice and water cold, often for more than 3 days. It saves a lot on individual water bottles and trips to the frig to refill. This flask is nicely made and comes with various options for use along with straws and a nice cleaner brush. I have not had any issues with leaks. I did reached out to Customer Service for a small issue. Their response was unbelievable in today's standards. I heard from someone in very quick time and it was on a weekend. We discussed my issue and it was resolved in a very short time to my complete satisfaction.

Great bottle! I work from home on the second floor, so this allows me to bring all the daily water I need to my office each day (instead of making 2-3 trips each day). I filled it 2 days ago with ice water and there's a small amount of ice still and the water is very cold! I loved this so much I bought 2 more - a smaller one that goes with me in my car, and one as a gift. Highly recommend!! I also like having different lid options.

Cool flask is awesome but I noticed something different we purchased several different colors so we each had our own but when the purple black one came the black cover was different it only had a shoulder strap. But the others all had different but much nicer covers with a shoulder strap, hand strap, and a finger or key loop and covered the entire body of the bottle also the bottom unzipped for ease of removal not sure if they changed the design or if the cover or if someone mixed it up when packaging it the design of the cover is much nicer on the other bottle covers maybe just an Amazon packaging difference go to Coolflask website get the original. Much nicer my water had ice in it for at least two days. Gave all the other bottles a 5 star but this one gets a 4

I bought this brand 3yrs ago. It keeps my cold beverages very cold over 12hrs. Unfortunately the top got real smelly 1.yrs in. Thank goodness there's 3 tops with this product. Great price, beautiful colors, fast shipping and easy to clean. I bought two more, I need one more and I'll be set.

I purchased the 64oz one back in 2023 and again in 2026, and let me tell you, this product works amazingly! It keeps ice for about 3 days. I loved it so much I had to order three more: one for each of my children and an extra one for me. These glitter ones, purchased recently, are so pretty, and the glitter stays intact after washing. Buy this product; you truly will like it as it really does work.

Love the color of the bottle when it arrived it is made well and kept my ice water cold all day long. The only thing I did not really love was the cheap plastic straws. Other than that, it was great.

المنتج عظيم ومفيد وسهل الحمل والتنقل ويحفظ البروده بشكل جيد ولكن ماهو لساعات طويلة. للأسف المنتج جايني بإكسسوارات ناقصه، ناقص غطاء واحد من اصل ثلاثه ناقص مصاصه وفرشاة التنظيف الخاصه فيها، لولا هذا النقص اعطي المنتج 5/5 تحديث: تواصلو معي وحلو المشكلة مشكورين 🙏🏻

للأسف ما تحفظ الحرارة شوي وتبرد

🧊 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.

Värt priset! Bästa vattenflaskan jag har ägt, vattnet håller sig iskallt i 24 timmar och kallt i 24 timmar till. 5/5
