Review on Black Hydro Flask Insulated Water Bottle with Wide Mouth and Straw Lid for Sports by Drew Gengler

Good: the cap fits my Hydro Flask perfectly - the quality of the product (cap and straws) is excellent as you can expect from a Hydro Flak product. Cons: However, the movable mouthpiece (the part that opens/closes) never closed tightly in the open position, so a significant amount of air escaped with each use. I double and triple checked to make sure the seal between the straw and the inside of the lid wasn't the problem. It's not like this; It is evident that the mouthpiece did not have an opening position that closed properly to allow the contents of the straw to be sucked in without a large volume of air. I'm sure this was probably due to the defective mouthpiece I received and not the general quality of Hydro Flask products, but I wanted to share.
