Mint Hydro Flask

by Jazzman, from CA, United States Written on September 16, 2018
I love my Hydro Flask! It's visually appealing and I have had no problems with it. It is also very easy to carry around and it is really convinient. It is somewhat pricey but it is an investment I was willing to take and I have no regrets buying it.
Best Used for:
  • Cold, Refreshing Water, Hot Coffee, Hot Meals, etcetera

Hydro Flask

by CDF, from AZ, United States Written on September 13, 2018
Would have given this five stars but it arrived dented. Looking Forward to receiving a new one. Keeps water cold for hours. Ice lasts over 12 hours. Added the straw lid for easier use. Is a little heavy. Nice size 40 oz. to last through the day.

Solid and reliable

by Jerico C., Verified Owner from Philippines Written on October 13, 2017
Keeps our water cold when we need it cold and hot when we need it hot.A bit heavy but the pros outweighs (no pun intended) the cons. This always goes inside our bag whenever we travel and hike mountains. Highly recommended!

Flask works great.

Hydro Flask works so well keeping water ice cold. Enjoy having the larger flask but like the optional straw top.

Hydro Flask rocks

by Debbie B., from NC, United States Written on August 28, 2015
I love my 40 oz wide mouth hydro flask! I fill it about 1/3 full of ice and then add water. I still have ice at the end of my eight hours. I leave it on top of the breakroom refrigerator. Sure beats my Nalgene and all the ice gone within my first hour of work!
