The 22oz bottle is the perfect size for gym equipment cup holders, has a flip straw top, and the insulation is top tier which makes this my ideal water bottle of choice for the gym. It holds ice longer than the competitor brands stainless steel insulated water bottles that I have. The feel of the bottle is nice and the flow of the straw is perfect. The vibrant coral is cute and even better in person. I love that it came with the perfect sized straw cleaning brush.
