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.

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 Got a free replacement, Great customer service [This review was collected as part of a promotion.] My hydroflask suddenly stopped retaining heat. Did the test at home. Contacted company about it. Got a quick response to send some photos & eventually ended up sending back the bottle for their inspection. Got a reply back a few weeks later that they are sending a new bottle. Love my replacement. Thank you!

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!
