Convenient, cute, sturdy tumbler
I used to carry a 40 oz HydroFlask bottle with me everywhere I went and would keep in on my desk at work. I've been working remotely lately and thus have no need to have a sealed bottle, so I picked this up on a whim after being enamored with the color (I have the cream colored model.) It has the expected HydroFlask quality and sturdiness, holds ice for hours and hours, and fits nicely in the hand. Unscrewing and replacing a lid isn't that much work, but I'm really surprised at how much more often I take a sip of water throughout the day now that I can skip that and just use the straw. My only complaint is that 20 oz feels a little small in capacity after being used to 40 oz, but maybe the fact that I have to keep getting up from my desk to refill it is ultimately better for my health in the long run.
great!
Love the tumbler and the straw lid, however the pictures do not compare to the colors in real life. I ordered the wisp grey and it was a tan, sandy color, the lid was grey and the straw and logo were brunt orange, red ish.
Hydro flask straw cup
I love this Hydro flask straw cup. The colors are amazing and I use it almost every day
New tumbler
I enjoy using this as a tumbler only; I tried the straw attachment for a couple of days but it was not "my thing" although it is well made. The tumbler material is solid, already took a drop from 3-ft onto gravel, just a small nick near the top edge. During the time I used the straw attachment it held liquids well, top part is flexible, I bit into it and did not crush or collapse the straw. At first it was somewhat challenging to place straw portions into the lid orifice, one must twist and push the top as it goes in; the bottom straw went in just fine.
Good cup
My daughter is a hydroflask superfan and we added this to her quiver. She is a fan of the lid and straw design.
Fantastic tumbler!!
So happy to finally get this tumbler!!! Love the design and simplicity of use and washing!!
Convenient and lives up to it’s hype
I love the convenience of the reusable straw for taking sips while in the car. Both for hot ( stays hot for hours) and cold drinks. The lid is very secure and wide so filling with ice and liquid is a breeze’
Keeps it cold, but hard to drink
This is definitely hydroflask quality. The cup is sturdy and powder coated. The straw is a great size. Its very hard to drink out of though. I think it seals too well which makes sucking almost impossible.
Hydro Flask
I use this cup everyday! I just put water in mine but it's great to have while at work or running errands. I love the color combo and the straw the best.
Great cup!
Great cup as usual! Great hydro flask product In general! Love the unique exclusive color!
