Special order items take longer to ship

We want to make extra-sure you realize that you've added a special order item to your cart. These items take a little longer to get to you because we have to order from the manufacturer first. The "Est. Ship Date" is the date we expect items to leave our warehouse... so add your chosen shipping speed to see when it will show up at your door.

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 Great size for on the go Great water bottle that keeps water cold all day. Perfect size for on the go and fits in a backpack sleeve as well as a cup holder in the car.

Rated 1 out of 5 by from Dented bottle My 13 yo has used 4 times. Dropped it twice and now dented and the plastic lid broke. Poor quality and over priced .
Date published: 2023-01-12
Rated 5 out of 5 by from Great gift This was a gift for my grandson for Christmas. He asked for it and was very pleased to get it. That's why I gave it 5 stars. I didn't use it myself.

Rated 5 out of 5 by from Very good water bottle Keeps water cold, use it daily, be careful it does dent easy
Date published: 2023-01-09
Rated 4 out of 5 by from Almost 5 stars Hydroflask makes a good product , but gave it a 4 due to cost and unlike several of their competitors...it doesnt come with boot . Have to buy boot separately. I want boot for it to reduce noise , reduce denting , and I feel it increases stability a bit

Rated 5 out of 5 by from Great Canister Works great does the job well. Keeps water fresh and cold
Date published: 2022-12-29
Rated 4 out of 5 by from No boot ? Only reason to give a 4 vs a 5, is had to buy the boot separately. Some of the competition ( I own quite a few ) includes them. The boot reduces dents , I feel it improves stability , reduces noise, and keeps bottle looking better longer . Would think it'd be standard , not additional cost.

Rated 1 out of 5 by from Leaky lid I have ordered 2 of these and they both leak! I am very disappointed in this product

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!
