64 oz Water Bottle Insulated with PU Leather Sleeve & 2 Lids | Half Gallon Water Jug Stainless Steel Triple-Wall, Cold 48+h/Hot 24+h, Dishwasher Safe, Leakproof, BPA-Free, for Gym & Hiking

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.

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.

This was fine in the beginning, had no issues with leaking until months later and it started puddling up in the lid even when standing up. Sort of easy to clean, it’s hard to get around the straw part on the lid. Ice lasts maybe 4 hours max. Stays cool for a while. Quality is nice, size is great goes up to at least 7 cups maybe 7 1/2. I love the carrier for it and makes it easier to carry around but I’m definitely going to be investing in another one for the longer use of ice.

Really nice! It does the job as advertised. The included accessories are a nice touch - especially the carrying strap. I’m trying to use less plastic. Instead of using two or three plastic water bottles at work, I’m refilling this at home. It will pay for itself in short order. Looks great, durable, and a great price especially as compared to some brand names. Definitely recommend.

I don’t write reviews often but I need to tell other ppl how truly good this water bottle is. It keeps my ice intact for about a day and a half-2 days, super durable ive dropped it many times and it barely dents, comes with the carrying case which is super nice, the straw is easy to clean bc you can detach it from the cap part, and very nice color. I also love the penguin design it fits the bottle so well. If i could give this 6 stars I would, I tell everyone around me to get one of these bottles its so good!!

Keeps water cold forever! Love that I don’t have to tough the straw with the flip mechanism!

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

Amazing water bottle. Fill it up with ice and the ice stays for 4 days!!! Its very versatile with 3 or 4 different bottle lids. My preference is the straw lid due to sensitive teeth. The only down-fall is with the straw lid it doesn't stay open all the way while drinking, so you have to hold it open with your teeth while drinking. But other then that, love it!

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.
