Standard mouth bottles have a narrower opening, which is easier to sip from and fits in cup holders, while wide mouth bottles are easier to clean and better for adding ice.
Q2: Are stainless steel water bottles dishwasher safe?
Most bottles are hand-wash only, but many brands offer dishwasher-safe lids. Always check the manufacturer’s care instructions.
Q3: Can I use these bottles for hot beverages too?
