Great bottles!
[This review was collected as part of a promotion.] The bottles are worth every penny. I use 9 different bottles in my daily activities. I recently had an issue with two of the lids and got great customer assistance from the company.

Standard Mouth Flex Cap - Black,
[This review was collected as part of a promotion.] Wrong size. I need a smaller cap for one of the very first hydro flasks made - when then just came out in Bend, OR. I was very specific about size. It is less than one inch in diameter inside the lid. Are these lids still available?

Give yourself options
[This review was collected as part of a promotion.] Buy your flask with the flex straw and add the flex cap to your order. Glad I have the flex cap option when I'm traveling or at work to take a break from my straw cap. Happy I made the choice to add this to my order.

Our 21 oz, insulated flasks are our favs but over time, water got into the caps and the standard rubber ring developed mold. Took it apart & cleaned it, but the seal is discolored & water is difficult to remove from cap. Will new design solve this?
