I got this new Ninja water bottle to use on my Summer outdoor adventures with my grandchildren and I love it. I put some flavored carbonated water and ice in it around noon and it was still ice cold and fizzy at 8pm! It still had ice cubes in it! I was amazed and refreshed at the same time after an afternoon of hiking! The mint color is very nice too! The carry strap makes it easy to handle an I love the attached lid.
