Simple Modern SpongeBob 14 fl oz Insulated Stainless Steel Summit Water Bottle with Straw Lid | SpongeBob Bubbles

I bought this for my son because he needed his own water bottle. He is three years old and it is very easy to use, and he loves the design! So far I haven't run into any problems with the straw, although cleaning straws will always be a pain. He's dropped it a few times already but it hasn't received any damage apart from a light scratch on the outside paint. I've been impressed with how long it keeps the water cool because we don't put ice in our water, and despite sitting in the sun for a few hours and being hot to the touch on the outside, the water inside was still cool.

These are by far my favorite water bottles for my almost 6-year-old. We've been using them for several years. Keeps liquids cold for quite a while, great design, completely leak-free. My favorite part is that the 3 pieces (bottle, cap, and straw) come quickly and completely apart and make for really easy washing and minimal (if any) mildew/mold issues in small parts. (I put them all in the dishwasher, top-rack, even though I think I'm supposed to handwash some and haven't had any problems.) Daughter takes them to school every day. Fits perfectly in the side pocket of her bookbag.
