Love this water bottle - worth the purchase

I have two Thermoflask bottles and I love them both (this is my second bottle). I take a clip and hang it off my bag and it has held up well. I also use these bottles in the summer and whenever I go on trips. Every time I fill the bottle with ice, it will still be there a few hours later, to the point where there is still ice. It keeps the ice lasting for longer, making my water cold, even for the next day.I would take this bottle into the hot blazing sun and the ice is still there by the time I get home after a long workout in the sun, with the bottle sitting out in the heat.I also like how there are two straws and another lid option, just in case I would like to switch it up to something else.Worth the purchase!

It does all the thermal things!

I originally bought this because of the spare time since my last thermal bottle's top tragically broke when I dropped it. (The cap fitt perfectly). The quality is great! I know recently they might have changed the sipping lid - I have a rubber tip but I've seen the most recent version have a full black plastic one, which is disappointing. I've dropped this beast and besides some dents and scratches, it hasn't leaked.On hotter days, the ice in the thermal lasts for most of the day but definitely benefits in an ice refill. In the wintertime, the ice will stay in the thermal for more than a couple of days. The top does condinsate even if the bottle itself won't on hotter days so your bag may get went.It's definitely easy to clean but it being 40 oz it'll not fit in many cup holders. I can fit most ice cubes into it given it's not an ice mold made for whisky (big chonk ice). Overall I would recommend from the bottle that I have right now.

Keeps ice cold drinks cold for more than 24 hrs still has ice

Great product and brand for cold drinks . Highly recommend the hot beverage mug. Leak proof and easy to carry but the bottle is not lightweight but it is worth the weight and price point over the stanley cups

Great Bottle, Lid Surpassed Expectations

The ThermoFlask Insulated Stainless Steel Water Bottle with Chug Lid & Straw Lid 40 oz, Cobalt starts out as a decent value for the price. I paid $25.49 for mine, which is comparable to the Kodi brand 32 oz bottles sold at the local grocery chain. The bottle is a dual wall vacuum insulated design with an attractive paint color. That seems very durable and long-lasting.I did have concerns about the lid. You get both a straw lid with flip-top, and a dual "chug" lid. Those are just plastic, with a small rubber seal to reduce (not eliminate) leaking. The smaller flip top tightens down pretty securely, but the overall lid is very inexact when attaching to the bottle. There's no stopping point, so you feel like over-tightening is going to strip out the plastic. There's no metal threads on the top, just plastic. I haven't tried to see how tight it will get, because I don't want to ruin it. When I tightened it as much as I felt comfortable, it still leaked.Going on a long camping trip, the bottle held up well. I had it in the side pocket of a backpack, so it was not tilted or challenged in terms of leaking. It kept my cold drink cold all day. The insulation works well, and overall I was very pleased with it. I'm still not 100% sold on the long term durability or sealing of the plastic lid, but for the price it was a nice, big, insulated bottle that does most things well. I would probably buy it again.NOTE: The product title and listing details clearly state "Dishwasher-Safe Reusable Bottle & Lids," but you can see where it says "Handwash Only" on the bottom of the bottle.

44 oz Thermos Stainless

I like most that I can dump ice in the mouth without much resistance. I have trouble holding it when its full because of the weight and smooth exterior. I haven’t found a Silicone boot to put on its base.Overall I do love this flask and am glad I didn't buy a gallon size. This with my 32 oz. gets me through half the day before a refill which works out fine so I can add a little ice. If I fill to the top with ice it will stay cold for about 2days if not shaken like in a car. If planning for a refill its best to use half ice or less to have more water or it will stay a block of ice without much water. The twist on cork is great for nighttime and don’t have to turn on a light to drink. The straw bottom doesn’t do well with ice unless the ice is melted to get straw through and close. I will probably cut my next beverage caddy’s bottom off and slip it over the outside since it looks better than a sock to make a better grip. If it had some rolls on the outside it would make for holding easier from the trunk rather than hold by the loop that I keep imagining snapping off by dropping. Might look up knots to tie a proper lanyard around it.All in all I am very happy with the flask and like the blue color. I was unhappy with the jerks in shipping that keep trying to pass off the unboxed bottle without both lids.
