Size Matters

[This review was collected as part of a promotion.] I purchased 2 of the 40oz Hydro Flask and love it and so does my husband. I hiked 5 miles last weekend in the desert and it was just enough to carry me through. I chose this company because they support SaveUSFS. org and they have excellent products.

Love Our Bottle!

[This review was collected as part of a promotion.] This is a perfect size for being out and about. We leave it in our car while doing errands or day trips and we know when we get back to the car we get to have a nice cool drink. It’s a bit heavy to carry with us at times (will have to think about getting the new micro sized ones). Love that Hydroflask thought of making small sized bottles with the same insulating properties. These bottles takes a beating cuz we use them nearly everyday and they hold up really well.

Great Purchase

[This review was collected as part of a promotion.] I love the product. Keeps items cold for a long period of time even without adding ice. If the item is previously chilled. Would definitely purchase again

The Best Waterbottle! The Water

[This review was collected as part of a promotion.] The best waterbottle! The water flow is great and it’s lightweight!

Fantastic Water Bottle

[This review was collected as part of a promotion.] Fantastic water bottle, I had purchased 2 but lost one immediately to my wife. as it added Benefit our icemaker makes craft ice balls. They fit perfectly and stay well over 24 hours. Now I just have to find some stickers to differentiate between the bottles. I had decided to purchase because I had received a 24 oz mug from my daughter as a gift , and from day one, I didn’t want to use any other mug. Thanks so much. !!!

Not The Same

[This review was collected as part of a promotion.] Returning customer and this time the bottle is up to par what it use to be. Does not keep bottle cold for the duration of what it’s stated

The Top Leaks

[This review was collected as part of a promotion.] The top on this bottle leaks even when crank it down tight. Seems like the older design was more leak proof.

Not The Best Water Bottles

[This review was collected as part of a promotion.] I’m very disappointed in this product. Bought one for me and my daughter and when you use it it leaks down the front of you. .

Wide Mouth With Flex Straw Cap.

[This review was collected as part of a promotion.] The insulation works really well. It keeps my drinks cold for hours, which is perfect for long days at work or when I’m out training. I haven’t had issues with leaking, and the lid design is secure while still being easy to open and close.

Beautiful Color! I Really Like This Water Bottle

[This review was collected as part of a promotion.] We've used HydroFlask bottles for about 10 years and love this brand for its ease of cleaning and clean third-party test results for its stainless steel.

Absolutely Amazing

[This review was collected as part of a promotion.] This was the perfect water bottle for me. I absolutely adore it. Best purchase I’ve made so far.

40oz Hydroflask

[This review was collected as part of a promotion.] Excellent !!!!! Great for travel , hiking , kayaking & outdoor excursions…. . loving the personal logo !!

Hydro Flask - Changed The Size Of The Font

[This review was collected as part of a promotion.] This is our 5th or so order and we always have these engraved for family members. Helpful so boys don't lose them. The prior font fit with the size of the water bottle and was honestly very nice and stood out. LOTS of compliments and made them easy to spot. The current font is super small and doesn't look right on a 40oz bottle. We were surprised and disappointed at the change, especially since the price has gone up. Quality of the Bottles is still great, but wouldn't pay the extra for engraving again.

Finally, A Good One

[This review was collected as part of a promotion.] I am getting rid of my lesser water bottles. This one really does keep cold liquid cold and the hot ones hot. Great for my round of golf.

Keeps Water Cool

[This review was collected as part of a promotion.] Not my first Hydroflask, but the drinking straw lid, the straw does not stay open unless you put your thumb on the spout while drinking, otherwise you suck in air. I like how the spout snaps down into the lid.
