Flex cap water bottle
This is the second bottle I’ve bought. Just the right size, keeps the cold cold and love the colors it comes in. It’s also very tough in structure. Will last a long time. The price is reasonable also.

Avoid - abort- do not buy
[This review was collected as part of a promotion.] Awful. Got the “leak proof” item and it leaks all the time. Followed the instructions double checked everything. Hydro does not do returns or refunds, once you find the product is garbage they say too bad, it is used.

Amazing Warranty
[This review was collected as part of a promotion.] After years of use I noticed a rusty looking stain so I requested a replacement under the lifetime warranty. A few steps later and now I have a new bottle that will last me years! Great company that stands behind their product!!!

Miss the Standard Sip Lid
[This review was collected as part of a promotion.] Hydro Flask no longer offers the Standard Sip Lid, and I really miss it. I have to use a lid from another water bottle when I use this water bottle for the day.

Difficult lid
[This review was collected as part of a promotion.] The lid doesn’t twist on or off easily and makes a horrible noise when turned. It’s also not easy to remove in the car while driving, but that’s my fault for not thinking it through before purchasing.

[This review was collected as part of a promotion.] This is a Christmas gift for my granddaughter.
She’ll receive it Christmas Day. I’m sure she’ll love it. It’s what she asked for.
