Review on BUILT Cascade Tumbler 24oz - Sleek Black Design for Optimal SEO by Victoria Smith

I got this 24 ounce bottle for my son when he outgrew his smaller 14 ounce vacuum flask. In terms of cold water it works as expected and we haven't tested it with hot liquids so can't comment on that. He takes water with him early in the morning and when he arrives 6 hours later the rest of the water is still cold. The bottle says 24 hours, but we didn't test that part either. Overall my son really likes the bottle as he hangs it on his backpack by a carabiner and simply unscrews it when needed leaving the cap attached so it doesn't get lost. He likes tactical black and that's what I got. It has a textured grip so it's great and great for his little hand.
