Hydro Flask Lifer!
[This review was collected as part of a promotion.] I love hydro flask. I have many colors and wanted to add a nice pink shade to my collection. Reef is NOT PINK. Was very disappointed in the color. It appears to be pink online, but it is more of a dark mauve, faded purplish burgundy. *see photo

Replacement bottle
[This review was collected as part of a promotion.] It did not have the rubber base protector to prevent the rust and cracking that my other bottle has.

2nd one owned
[This review was collected as part of a promotion.] After almost 15 years of hard daily use, the 21oz bottle gave up the ghost. I hope this next one lasts just as long.

Great bottles !
[This review was collected as part of a promotion.] love your bottles and this is a good one despite the color. It is more gray than I thought it would be. My favorite is the 22 oz. Very similar !

Hydro Flask
[This review was collected as part of a promotion.] Best Flasks made. This is our tenth one. 10 means you can have a couple of days free from washing them.

Good size
[This review was collected as part of a promotion.] Perfect size for me, and fits in cup holder in car. Wish there was a straw lid, had to buy one separately.

Do they float? I'm looking for something with a closed lid to use on my kayak and with the possibility of flipping the kayak I would like to make sure I will be able to locate the flask if that were ever to happen.

I am getting a metallic taste in my water from the 21 oz flask. I’m surprised as it has 18/10 stainless steel. Is there anything that would get rid of this? Â

Is there a cap available for purchase that would allow me to use my standard mouth Hydro Flask 21oz with hot drinks? I purchased 2 hoping to use one for hot and the other for cold. However I have not been able to use hot drinks due to the cap. Frustrated
