Coldest 40 oz Tumbler with Handle and Straw, 100% Leak Proof Insulated Tumbler with Lid and Straw (3 Lids), Stainless Steel Tumblers for Women & Men, Cup Holder Friendly, 46 oz (Camouflage Flag)

Tie-dye color is gorgeous (nothing like marketing pics)
Coldest tumblers feel very aggressively over-marketed to me and whoever is in charge of taking pictures for their packaging should be sacked, but they are legitimately wonderful water bottles if you find a color you like.Here’s why I am absolutely head-over-heels for my tie-dye 36oz Limitless tumbler:* The tie-dye coloring is GORGEOUS. Go dig through the customer images, because the pictures shown alongside the product description must be 3D renders; they look absolutely nothing like the real product. I originally ordered their green/purple “interstellar” tumbler, but it was far too fabulous for me (turns out it has an iridescent glitter coating, which doesn’t translate in pictures but is incredibly in-your-face in person). Fortunately, I discovered the customer photos of the tie-dye tumbler and haven’t looked back.* 36oz is a large amount of water, and easily works to share. It will last me pretty much all day if I’m the only one drinking it, or I can take it in the car to share with my wife (the kids have their own water bottles).* It fits really well into my car’s cup holder, but isn’t so over-large that it runs afoul of the dashboard (I’m driving a Chevy Bolt, FWIW).* The rubberized bottom keeps it nice and steady on otherwise-slipper surfaces like tile.* The side handle is absolutely necessary for a water bottle of this size/weight. That alone makes this particular bottle in the Coldest line a no-brainer, IMO.* This is one of the few Coldest water bottles that has tasteful branding (just a small “COLDEST” logo near the bottom, and it’s facing the drinker if you’re right handed).* Three lids! I’ve admittedly only used the folding straw lid so far (make sure to cut the straw at an angle! Mine was almost exactly as tall as the water bottle, and I could barely get any water up it; once I clipped it, I’m getting huge gulps, to the point that I haven’t bothered to try the gulp lid), but it’s nice to effectively have three water bottles in one.* It really keeps water cold for a long time! I’ll typically fill it 1/3 to 1/2 with ice, and that will easily last 24+ hours. My other stainless steel insulated water bottle (from Camelbak, FWIW) will only keep the ice as ice for about 12 hours; this one I can fill in the evening and it will be perfectly cold right up until the next evening. My wife actually doesn’t like using it because the water is a little too cold for her tastes; more for me!* The folding straw lid has been spill-proof for me. A little bit of water occasionally will leak out if I don’t let it drain completely before flipping it shut, and of course I’d probably want to use the gulp lid if I’m going to let the bottle float around a bag (since something could conceivably flip the straw up), but I haven’t had any leaks after the water bottle falls over from sitting on the couch, shaking it to even distribute the ice, etc.That said, there are some potential downsides that you should probably know about, as well:- NOT GOOD FOR LEFTIES! The way the bottle is threaded and the position of the handle mean that if you’re left-handed you basically can’t use anything other than the always-open straw cap and drink out of it comfortably using the handle.- It’s kind of fiddly to clean. I ended up buying Coldest’s bottle brush collection (they really got me good). It works great, but the ordinary bottle brushes we had floating around the house absolutely weren’t up to the job. I wouldn’t want to use this bottle for hot drinks or things with sugars and similar.- The design is necessarily kind of top-heavy to allow for use in cup holders, so it doesn’t sit very well on carpet and other uneven surfaces.tl;dr this is a fantastic water bottle, but you can’t trust the official pictures when it comes to coloration.

Great product
Just what I needed. keeps my water cold for a very long time even after the ice has melted. There’s no spill if it flops over or dropped. I love the variety of tops that comes with it.

BEST CUP EVER BUT NOT 40oz!!
This is an excellent cup! I put 24oz of LeCroix in my cup and filled the other 12 oz with mostly melted ice. The next morning the ice was still there. That’s really amazing. love that it comes with three different tops which makes it really convenient for any use. The only con is that is is not 40oz. The first line is the ad states it’s 40oz. It does say further down in the ad that it’s 36oz but if you don’t read it all the way down you wouldn’t know that. The only coldest cups I found are 36 or 46 oz. I have no idea where they get 40oz from but it’s very misleading.Having said that, I love this cup so much I just ordered another one.

It what I thought.
When advertised for 13 hours keeping liquids hot, it is not taken into consideration that you need to open the lid to take a drink. Every time you open the lid, heat escapes. Therefore it may only keep liquids hot if you don’t drink from the tumbler. Hence, it does not keep liquids hot for 13 hours. It get less warm every time you open the lid to drink. I bought this for coffee, but the lids to the vessel are not conducive for coffee. It is terrific for cold water. I guess that is my fault for not purchasing a mug.The tumblers are beautiful. However, the biggest problem is that they are top- heavy and will fall over. They are great when in a cup holder. So overall I’m not thrilled with the product. I will probably keep it and use it in my car for water. I don’t see any better performance than my other tumblers., Primula, RTIC, ETC.
