      Rated 5 out of 5 by from My Favorite Water Bottle Ever I won the water bottle at an event last year. I've been carrying it pretty much every day since then. It maintains cold water for hours. It's pretty easy to clean. I've dropped it few times and it only has a small dent, that is very unnoticeable. I need purchase a larger one to fit my water intake needs.

      Rated 4 out of 5 by from Much needed cap but not leak proof. I always use these caps. I just wish they were a bit more leak proof. The description does say it is not leak proof so it’s just a wish for me.

    • 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.

      Can you wash these?

      We do not suggest putting your flask through the dish washer. For cleaning, we recommend hand washing with a bottle brush and mild dish soap.
