      Can we purchase a 18 oz bottle and have a straw lid as an option?

      Asked by: aed2018
      It would have to be the wide mouth flask. The straw cap will work with any of our wide mouth flasks.

      Can you use a top made for hot beverages on the standard-neck water bottle?

      Asked by: hallie1
      The flip cap would not fit a standard mouth flask. The only two caps would be the sports cap and the standard mouth flex cap.

      Is the stainless steel finish also sweat-proof like the powder paint finish? Any differences between the 2?

      Asked by: Kat 68
      The only difference is the stainless does not have the powder coat.
