  • This may be my perfect bottle
Color: Cobalt Size: 24 oz Style: Bottle
Easy to clean and fill. I put ice in my drink in the evening, and when I go to fill the bottle in the morning, there is still ice in it. When traveling on a plane, my previous bottle sprayed liquid everywhere if I opened it aloft because of the pressure differential. This one opens a tiny little vent hole at the top before connecting the straw, so the pressure is vented without causing a calamity. It's sturdy, and I've washed it several times by hand and in the dishwasher without issue. Holds a goodly amount of liquid. And it cost significantly less than another brand (my wife bought one) that looks just like it. So what's not to love? ... show more

  • It does all the thermal things!
Color: Cobalt Size: 40 oz Style: Bottle
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. ... show more

  • Robust and keeps liquid cold all day, or more
Color: Black Size: 24 oz Style: Bottle
I have had this flask for several months now and it stands up to a lot of fairly rough treatment. The coating shows only a very few minor scuffs despite being dropped, rolled around in a metal cart and subject to extreme Texas summer temperatures. It has kept liquids cold every day all summer, even when left for hours in the car in direct sun. I've even found that water stays cool into the following day. I'm a volunteer at an Animal Sanctuary and need to stay hydrated while out helping with their care, so its important to keep hydrated while outside. It's great to have liquids that stay cold all the time that we're out in the open. ... show more

  • I love my new water bottle!!
Color: Blue, Black Size: 24 oz Style: Bottle
This is an awesome alternative to the more expensive hydroflasks. I give 4 stars for leakage cus it does happen sometimes, however it’s most likely cus I didn’t tighten the lid enough. If you fill it to the brim you might be attacked by the straw-part as it can shoot up water after you sip (which is normal since it uses pressure for easy drinking) Definitely get this if you need an easy bottle! It also comes with a spare lid and straw! ... show more

  • Thermoflask is the Best !
Color: Plum Size: 32 oz Style: Bottle
This is my second one different size. My favorite brand, you can drop them and no dents. I don’t put ice in them, just cold water and stays cold for several hours, never goes completely warm! Plus you get two different lids with container,

  • LOVE IT!!! Keeps ICE and drinks cold for more than 24hours
Color: Cobalt Size: 24 oz Style: Bottle
I have bought this item more than once because I keep misplacing them. No fault of the brand. So, I lose one and buy another. I'm hooked on this. It fits in the cup holder in my car. It won't spill on my desk. easy to fill. Comes with two types of lids. Straw version or 1inch opening to pour. Great buy for the money ... show more

  • Great Bottle
Color: Black Size: 40 oz Style: Bottle
This bottle is large enough without being too cumbersome to fit in a backpack side pocket. It stays cold all day, especially with a few ice cubes added in. I like the ability to switch lid types. The straw doesn't require you to tip the bottle to drink. It also has a small vent so you can sip through the straw continuously without any added pressure. The straw is also easy to remove for cleaning (but doesn't come loose on its own). The bottle opening is large enough that it is easy to clean without a special bottle brush. I was hesitant to spend $20 on a new water bottle, but I don't regret it and now I'm even considering buying a second one. ... show more

  • Okay
Color: Cobalt Size: 24 oz Style: Bottle
While I really liked this water bottle for some time, it eventually started continually growing mold in the straw and cap even though I cleaned it very often. The straw i was able to clean out, but the top just wasn't ever able to get fully clean. Otherwise this was a great water bottle.
