Hydro Flask Temp Shield
You worked hard to produce the precise temperature and TempShield is here to preserve it. Thanks to double wall vacuum construction, TempShield technology protects the contents of your bottle from the elements so you can enjoy your beverage as intended. This design keeps your refreshments cold for up to 24 hours and your hot drinks hot for 6 hours. Whether it's hot or cold on the inside, you wouldn't know it because the temperature won't transfer to the exterior.

Rated 5 out of 5 by from Hydro flask [This review was collected as part of a promotion.] I received this product in exchange for my honest review. First off the color of this bottle is beautiful. Second, whatever you put in it stays cold all day long along with the ice. Great for long trips for hiking

Rated 5 out of 5 by from Keeps it cool [This review was collected as part of a promotion.] This hydro flask is perfect for both cold or hot drinks. I use it mostly for keeping my water ice cold but I have also used it for coffee in the past. The color really makes it unique. All of their products are good quality.

Rated 5 out of 5 by from The best waterbottle [This review was collected as part of a promotion.] I love my hydro flask. The color is cute, the size is perfect (not too bulky or small), and most importantly, it keeps things cold. I’ve tried a lot of other brands and nothings keeps my water iced longer than a hydro flask. And they’re super durable and last for ages. Highly recommend

Rated 5 out of 5 by from Great water bottle! [This review was collected as part of a promotion.] There are so many things to love about this water bottle. It has such a minimalistic and sleek design, and the color is very bright. It's the perfect size for urban day to day use. Its tall and skinny design makes it easy to carry around, and it fits in my car's cup holder. I like that it has a carry strap so I can grab it or even use the carabiner to attach it to my bag or bicycle. The coat is grippy in texture so it is very easy for me to hold onto a bottle, but still slippery enough to slide into any pocket or corner of a bag. The lid is easy to open and close with sweaty hands and it's completely watertight. It really keeps your drinks cold/hot for said amount of time and the mouth is wide enough that I can put ice in the bottle as well as get a brush in there to clean it. Unlike some other bottles, It is comfortable to drink directly from because the threads are on the inside of the mouth spout so lips cannot touch screw threads. I definitely recommend this water bottle!

Rated 5 out of 5 by from Perfect size for an afternoon walk [This review was collected as part of a promotion.] I have different a collection of drink containers and this 21 oz standard mouth bottle is one of my favorites. I have one for different occasions and use - bigger bottles for longer trips or carry more volume, smaller bottles for a short walk or trip, gardening etc. It's harder to drink from larger bottles, especially if riding a bicycle or driving a vehicle or doing some activity - the 20-24oz size bottles are perfect. This came with a shoulder bag/strap which makes carrying the bottle much more easier/comfortable. The keeps cold and hot drinks - great for a cold water/lemonade or power drinks, or for coffee/tea. Good simple design - nice teal color on the bottle.

Rated 5 out of 5 by from Holds ice very well [This review was collected as part of a promotion.] This keeps my drinks super cold. My husband's ice in his bottle melted hours before mine did! I love being able to have a cold drink all day. My only downside is that the lid can be a little hard to open sometimes.

Will this particular bottle fit in a standard bicycle bottle cage?

Asked by: Jim M
Hey Jim! Good news: this can fit most standard cages! Load up with 21 ounces of ice and you have some ice cold water after a hard ride. Nothing can beat that!

Does the wide lid straw mouth cap fit the 21 oz hydro flask? 

Asked by: Sharbacker
Hey there Sharbacker, good question. For the 21 oz Hydro Flask you have three options; Hydro Flip Cap, Standard Mouth Flex Cap, and the Standard Mouth Sport Cap. Unfortunately, the Wide Mouth Straw Lid Cap is only compatible with the Wide Mouth bottles. Sorry, but I hope this helps!

Is this version dishwasher safe?

Asked by: BrAL
Hey there, thanks for your question. Yes, all Hydro Flask powder coated bottles are dishwasher safe. The only drinkware that doesn't have the powder coat from hydroflask are their coffee mugs with the handle, they have a more rubbery texture. I hope this helps!

Are you able to put ice in the cup easily? How wide is the mouth opening?

Asked by: Ellieirwin
Thanks for the question! I actually have this Flask and I can for sure fit ice in there no problem. I measured the width of the mouth and it is approximately 1.75 inches. I hope this helps!
