Not the best water bottles

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.

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

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.

Arrived damaged

It arrived with dark lines scuffed all over it that would not come out, and customer service refused to help. It was disappointing for a “new” item to come damaged.

Hydro Flask - Changed the size of the Font

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

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.
