Coolflask 64 oz Water Bottle Insulated with PU Leather Sleeve & 2 Lids

Thermal Performance & Insulation I’ve tested a wide range of insulated gear, and the Coolflask 64 oz is a standout in its category. The double-wall vacuum insulation is incredibly efficient; I’ve consistently had ice stay solid for well over 24 hours, even when the bottle was left in a warm environment. Whether you need your water ice-cold or your coffee piping hot for an entire day, this flask delivers on its "Triple Insulated" promise. ​Build Quality & Versatility The 18/8 food-grade stainless steel feels rugged and built for daily use. I particularly appreciate the powder-coated finish, which provides a secure, non-slip grip even when your hands are wet. What really sets Coolflask apart, however, is the inclusion of multiple lid options (Straw, Spout, and Handle). This level of versatility is rare and allows the bottle to transition seamlessly from a desk setting to a rugged outdoor environment. ​The "Power User" Perspective For those who lead a busy, on-the-go lifestyle, a 64oz capacity is a game-changer. It eliminates the need for constant refills and ensures you stay focused on your tasks rather than hunting for a water fountain. Despite its large volume, the ergonomic handle and sleek design make it surprisingly portable. It feels like a piece of "pro-level" gear rather than just another water bottle. ​Final Verdict Coolflask has nailed the balance between aesthetics, durability, and utility. It’s a sophisticated, well-engineered product that holds up to high demands. If you’re looking for a high-capacity hydration solution that doesn't compromise on quality, this is the gold standard.

This is my favorite water bottle because it holds 64 ounces of fluid, has 3 different lids, comes in some cute colors with a matching carrier. What really differentiated this from its competitors was the 3 lids and the handy carrier with straps. I never jumped on the Stanley water bottle trend because I didn’t want to spend too much on one bottle, but also because I prefer a wide mouth container with no straw. This one comes with 3 lids: a basic lid, a lid with a drinking spout, and a lid with a straw. I find the carrier helpful for toting it around. I bought the lilac color first then liked it so much, I bought the coral. It’s 64 ounces so I know if I drink the whole thing in a day, I’ve gotten my minimum requirement for H2O. It does all the things you’d expect like keeping cold water cold for 24 hours. My only criticism is I’d like CoolFlask to come out with more fun colors, maybe some ombré designs. Highly recommended.

This water bottle is so cute! It's def smaller than the regular 64 oz shape but it carry the same amount! I like the color and design and it's able to store cold and hot water for a long time. It comes with a cut carry bag and it's so cute and connivence. I use it to store super hot water and pour to cup to drink during the day but not sure if it's because the water too hot and the cap always has water dripping out. But overall I like it.

This thing is awesome. Sits in a hot tractor cab for 12+ hours in direct sunlight and still has lots of ice in it at the end of the day. Worth every penny

I really like this water bottle. The color is very nice, but it leans more on the girly side, which makes it a perfect gift if you’re buying for a woman or someone who likes cute colors. I bought it for my girl and she thought it was adorable. The size is great, it keeps drinks cold for a long time, and the extra lids and carrying sleeve make it even better. Overall, a really nice gift and a solid water bottle.

I've had my jug for 2 years now, using daily. I mean the bottle itself is steel, so of course it will last, but the sleeve with carrying strap has also held up well. The strap makes it so easy to stay hydrated everywhere. I take this jug everyday to work and even use at home; I empty it by dinnertime and ice is still remaining. I put about 8 cubes & fill w/cold filtered water, so that's impressive for it to last all day. I'm very particular about having ice cold water through a straw, and make sure to stay very hydrated. I have replaced the straw lid because I feel the one it came with gets gunky in the crevices I can't manage to reach. For being so massive, the bottle is easy enough to clean. Being a girly girl, i love the color and look of this bottle and even attached a cutesy keychain to the strap. I'm very happy with this product and have definitely gotten my moneys worth.

I have had this water bottle for about 3 years now and can guarantee you that with enough ice it indeed stays cold for a long time. I filled it with ice before going camping and three days later and only after adding warm water did the ice fully melt. The water was still cold that evening. I have dropped it multiple times and it has only dented and the paint has chipped. The only problem I've had with leaking is with the straw lid when it's overfilled. I have bought one for a coworker and convinced my fiance to buy one. 100% will keep returning for more water bottles for friends, family, and new colors.

I love this water bottle. I was in search of something which was insulated and also 2L size. This water bottle has been great! It has 3 different lids so you can pick the one that best suits your needs. I am someone who likes my water very cold and if you fill this in the morning it will genuinely keep your water cold all day even in the Summer heat. The carrying bag is also very convenient as this is a large water bottle it may not fit easily into another bag but also if you are going for a long walk or hike and maybe don't want to bring a full backpack the bag is great for freeing up your hands. The strap is long enough to comfortably wear cross-body. It's easy to wash and the colours are cute.

Really pleased with this drink bottle, it holds quite a lot and does keep the drinks cold, recommend.

Los líquidos duran bastante tiempo fríos, y es una muy buena capacidad de casi 2 litros. Es muy práctico ya que trae una funda para colgártelo como si fuera tipo bolsita. Además trae diferentes tipos de tapas para poder beber como más te guste. También me gustó que trae su escobita para lavar los popotes lo cual está súper bien, porque después de tiempo se ensucian. En general muy buen producto

Fue un regalo y le encantó!!

I love the compact form factor, it keeps water cold all day, and comes with tons of accessories. Super easy to clean, nice textured feel to the outside. The top tab of my straw lid had broken so I contacted the company for a replacement lid, and they actually just sent me a whole extra bottle and all the accessories. Awesome customer service.
