Coolflask 64 oz Insulated Water Bottle with Straw&3 Lids, Half Gallon Insulated Water Jug Galaxy Large Metal Stainless Steel Flask for Gym, Sports and Office, Keep Cold 48H Hot 24H, Starry Night

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.

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.

The color is super nice, I haven't tried something hot yet, but it does keep things cold for a long time. The container has very good quality, no leaks, and the size seems perfect to me I usually use it for long trips.

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.

I have a bunch of different types of water bottles similar to this. I love my bigger 64oz one but it is a bit of a pain when I'm in bed laying on my side reading. I wanted something smaller. This has a decent capacity, and the top with the fold out straw works well. I like that it's hard plastic, and not some rubbery substance that's overly flexible. It really does allow for good drinking and the vent to prevent vacuum locking works better than most. I also like the cover, since I can leave it in there and not worry about the rougher metal bottom scratching up wood surfaces. Not as good as my larger one for keeping things cold, ice cubes in this one don't last overnight, but it still keeps things cold enough.

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!

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.
