Defective covers

[This review was collected as part of a promotion.] The cover does not secure - both bottles leak when using

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.

Love the new color options.

[This review was collected as part of a promotion.] This was a replacement for a yellow bottle I bought several years ago. Love the darker yellow color choice.

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 !

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.
