Nice quality, and I love the colors. Keeps my water cold all night which helps because I'm pregnant and can't get enough. The sports top makes it so easy so I'm not fumbling with it.

Is the sip part of the cap made of latex?
BEST ANSWER: According to the hydro flask website the cap could contain latex
Is this kid for the 40 ounce hydro flask bottle?
BEST ANSWER: That is a sport top for a standard mouth size... not the wide mouth size. It will not fit your 40 oz hydro flask. You will need a wide mouth top.
