refillable water bottle

Refillable bottles range from small kid-friendly sizes up to very large bottles. Common volumes include 14 fl oz, 16 fl oz, 24 fl oz, 30 fl oz, 32 fl oz, and 62 fl oz.

Common lid and drinking options include wide-mouth openings, straw lids, flip-top and push-button lids, drink-thru and locking lids, and spouts or built-in straws for sipping or swigging.

Insulated stainless-steel bottles commonly use double-wall or multi-layer insulation; some product descriptions state cold retention of up to 24 hours.

Common leak- and spill-prevention features include spillproof or leakproof lids, locking or push-button locks, valves or seals that reduce leakage, and secure lid covers to protect the opening.

Several bottles are described as cup-holder friendly or explicitly state they fit most car cup holders, though actual fit depends on the bottle's size and shape.

Common protections include lid covers or push-to-open lids that shield the spout, straws that fold back inside to stay protected, and hinged lids that open fully for thorough cleaning.
