Coolflask Water Bottle 87 oz with Straw, 2/3 Gallon Insulated Stainless Steel Large 3 Lids Big Water Jug for Sports or Office, Non-BPA Keep Cold Up to 48 Hrs or Hot Up to 24 Hrs, Samurai Cyan

There is only one thing I can think of about this product I am critical of, and that is the small opening. As a person who likes to load their water thermos with ice, it is a tedious process. My previous water thermos which was half the capacity at 64oz had a bigger opening. But it's ability to keep things cool are excellent and helped by the carry case included, which is also a nice feature. I appreciate that it comes with 3 different lid types and 2 straws with a straw cleaner. Good build quality with textured outside surface. I rate this 4.5 stars which when rounded goes to 5. I would recommend this product but warn about the opening size.

AMAZING! I bought this in July of 2022. I have never needed a replacement. It's lasted 1000+ days, and I've had no issues. It keeps the water cold for almost two days! I keep it by my nightstand, so I don't have to go get a glass from my bathroom. This is probably the best $30 I've ever spent. 10/10!

This is a good looking and feature packed bottle. Different lids suit multiple likes and the well made fabric sleeve adds greater functionality when it comes to hefting around a lot of liquid weight. So far I am very pleased.

I was hesitant to purchase this after reading several reviews stating the lids don't fit or the drink doesn't stay cold. I bought this specifically to keep ice water cold during my workday. I won't fill it with anything else, so it should not need to be cleaned on the inside, really, ever. To avoid damaging a product that I might have to send back, I filled it halfway with ice and water and let it sit at home for the duration I was at work (9+ hours). When I got home, virtually all of the ice was still frozen, so I knew at that point I was likely to be keeping the bottle. I turned it on its side and up-side-down and it did not leak at all. Bonus. I filled it all the way up with ice and water and left it overnight. Started drinking my ice water in the morning, took the bottle to work, had only ice left after lunchtime so I used a bottle filler to refill it all the way. It laid down on my passenger seat at some point but the seat remained dry. Had ice water all the way to bed time and, when I finished the water, there was very little ice left in the bottle. 24 hours of ice meets my needs just fine. It is very sufficient towards my intended purpose and I am very pleased. The case that it comes in has a convenient handhold that allows for one handed drinking and the lid has a hinged handle that is convenient. It also came with a detachable shoulder strap that I do not need. I recommend this for someone who wants a large bottle that is functional to stay cold all day long. Totally worth paying half the price of the more popular brands. Do not let the poor reviews stifle your purchase. This thing is great!

Had this a long time now, it’s my daily water bottle. The temperature keeps amazing, at least for the cold, I haven’t tried anything warm. Not too many problems with leaking, but the straw and the mouthpiece have worn a bit and the I have to press down the mouthpiece and have it in the perfect position for it to work well, or it gets a lot of air. Super durable, I’ve dropped this thing out of my car onto the pavement more times than I can count. The carrying fabric thing it comes with is nice, but the zipper just keeps breaking in different areas, but small DIY repairs keeps it workable.

I live in the desert and I do commercial HVAC. My days usually consist of 8+ hours on rooftops in 110+ degree heat. This was the biggest one I could find, which is why I bought it. This thing has been wonderful, holds ice all day even in direct sunlight. I've seen people gripe about it rusting inside, but I've used it all summer and it still looks brand new on the inside. However I only use it for water and I rinse it out regularly. It's pretty sturdy, it's fallen out of my truck when I opened the door multiple times and it hasn't broken yet. If I had to complain about one thing, it's the diameter of the opening at the top. It's so small for such a large container, I actually chuckled at it when I first got it. It's kind of a pain to scoop ice into. Fortunately it holds ice well enough that you really don't need to add much

This bottle truly keeps water cold. I have filled it with ice and the ice remains there over night. Incredible! I’ve had no issues with the lid or straw. It seems flimsy but it holds well. No issues with leaking either. I also tend to just hold it from the bottom mostly since I bought the 87 oz one. I haven’t tried it with hot beverages but if it’s legit with cold than I’m sure the hot beverage keeps its temperature as well. Highly recommend!

This flask as it’s called is huge,my teenage sun loves it!Hes autistic and doesn’t like drinking out of a regular straw,cup,or bottled water top.So im upgrading his mug he’s had a few years just because he’s becoming a lot more flare savvy,and the other one just served it’s purpose.This comes with an extra sleeve that comes on the bottle easily taken off,2 straws that fit on the end of the top.A straw washer,well everything it says.I literally just got it and came straight to write a review he loves it,and I’m equally impressed.
