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 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. Read more
If you work outside in the hot weather like I do, this is the best water bottle on the market. Nice big size for your favorite drink and ice (for me a 20 ounce bottle was too small). It keeps my flavored water in ice very cold (I normally fill it two or three times daily so I don't know if it keeps things cold for 48 hours). The mouth is wide enough for standard sized ice cubes and slices of fruit. The stainless steel construction makes it sturdy, stain resistant, and has never leaked. The carrying pouch and strap keeps it from being scratched and makes carrying much easier. Highly recommended! Read more
This cooler is very nice. I only have a couple of complaints. The neck is a tad small, and makes it hard to pour things into. Lids are handy and have good options. Holds temperature for a long time, which is nice. I haven't had a leak yet, and I've used it to hold sweet tea and soda, so it works amazingly. Shoulder strap is a tad finicky, mostly due to how thin the band is. Over all I'd say this product is excellent value for money. And I most likely will purchase another one again. Read more
Stays cold for a couple days. A little bulky and the zipper broke after 2 days of having it. The pouch design seems really weak and it looks like the seams are detaching from the bag but still hanging in there. The different mouth pieces are awesome but the straw doesn’t go all the way down. It’s a pretty good gallon water bottle for the price. Read more
10/10. Amazing. If you are a very active person or someone who genuinely needs more water in your life, GET. THIS. It’s a game changer! Pros: BIG!! Can fit so much water or tea. Keeps my ice cold water cold!! And when I finish my water and the ice hasn’t melted, I have ice for like 3 days straight in this thing before it melts, LOL! Minimal scratching, unless you’re banging this water bottle to cement floor then.. that’s how you’ll get it scratched up. Cleaning? SO EASY! I LOVE IT! It’s easier than any other water bottle I’ve bought from here! Cons: Will get heavy. But I mean, what can you expect? It’s a big thick bottle. If anything it’s beneficial! Because when you walk around with this heavy item, you’re basically doing cardio. Read more
Love this water bottle. I have ice in it for days. I also recently had an issue with the handle breaking off on the lid. Contacted Coolflask via email and had replacement parts within 3days. I will be a customer for life. I have had not other issues at all. Read more
I absolutely love this jug, especially the strap. Makes it easier to carry. But, my loop broke on my main lid. How do I get a replacement? Temps- hold a long time. Carry bag thing gets loose so caring it by the loop and not the strap could leave to the case to fall off. But, forreal, how do I get the replacement lid? Read more
