Hydro Flask Bottles

This water bottle has an insulated sport cap so your drinks will stay hot or cold for hours without spilling! The ergonomic shape allows you to drink water with just one hand and the flow control spout makes sure you’re able to get enough water. The double-wall insulation of the bottle can keep your drinks cold for up to 24 hours and hot for up to 6 hours. Even better, it’s covered by Hydro Flask’s lifetime warranty!

These will hold ice all day long..so not only does your drink not get watered down (if it’s not water) but it is still refreshingly ice cold after a long day…great quality and worth the price!


I bought a 22 oz tumbler the last time Hydro Flask had a sale and my husband LOVES it and uses it every day.


I can leave these in my car, I live in AZ, so 120 degrees. Come back and the water is still cold after an hour. Love Hydro Flask!

    Not seeing the mint color, only the pink.

    • Amber (Hip Sidekick)

      Thanks for letting us know!

    Help, I’m totally not the cool mom. I know Hydro Flasks are the in thing for teenage girls right now. Is this the “right” one? Or is it a specific style/size?

    • Denise

      Hello. This is the ONE my 12 year old daughter “had” to have 😀. (Only in a different color)

      • Sara

        Thanks!

    • Bouncyb

      I believe for the teen “vsco” trend it’s the wide mouth 32 oz. But any hydro flask is a good one!

    • Susan

      My teens have both this size & the wide mouth 32 oz. They prefer the 32 oz wide mouth cause they dont have to keep refilling it (they refuse to fill it from the gross water fountain at school.) Most kids around here carry the 32 oz. They get stolen & resold too!!!
      I personally love this size cause it’s not as heavy.

    • MommySpendsLess

      I’m just a wanna-be cool mom 🙂 but the Tick Tock and YouTube videos my daughter has shown me show the regular lid, not the sports lid. I almost snagged this one anyway but then I read reviews that this lid leaks badly. By the time I bought the bottle and a $10 lid I would have been almost back at full price. I think I’m going to hold out for one of the screw top styles. (Especially since my daughter has a new, perfectly functional generic water bottle for school and only wants this because it’s trendy.)

    Many thanks for the heads up! i literally just bought 1 at full price at amazon for $34! my teen will def need this when school starts this week. I brought my 40 oz to Hawaii last week..the water remained icycold the entire time while sightseeing despite the humidity and heat.

    • Amber (Hip Sidekick)

      Oh awesome! You’re welcome, JC! Good to know how well yours worked for you in Hawaii! Thanks for sharing!

    • jaclynn esparza

    • Amber (Hip Sidekick)

  6. rosemary

    Are there generic brands that r cheaper but still work the same?

      • Jessica (Hip' Sidekick)

        Thanks for the tip, Coupon Katie!

    • Sara

      I have an Ozark Trail brand bottle from Walmart and it keeps ice for more than 24 hours and was less than $10.

      • Jessica (Hip' Sidekick)

        Nice score, Sara!

  7. shannon bradford

    only hot pink at this price

    • Jessica (Hip' Sidekick)

      Thanks for letting us know, Shannon! The post has been updated!

  8. Sherri5166

    Hot pink is okay with me, I made my order! Thanks so much!
    I ordered from Hydroflask on a post ya’ll had about a week ago and was looking forward to getting one. For some reason the money was put back on my card with no explanation as to why. I’m glad ya’ll found another deal on them.

    • Jessica (Hip' Sidekick)

      Oh no! I’m so sorry to hear that, Sherri! I’m glad you were able to snag one today!!

  9. Erin

    The lid on these starts leaking really quickly. Just a heads up. The wide mouth lid lasted a lot longer before it started leaking on me.

    • Jessica (Hip' Sidekick)

      Oh, that stinks, Erin! Thanks for letting us know your experience with these!
