freeflow autoseal water bottle

Listings show these bottles are made primarily from stainless steel and from plastic.

Filters are described as lasting about 4–6 months (approximately 80 gallons) and are said to replace the equivalent of roughly 600 single-use 16.9 fl oz water bottles.

Insulation features include a stainless steel body and double-walled construction; listings claim these designs keep drinks cold all day and extend cold retention compared with non-insulated bottles.

The FreeFlow design filters as you drink with no extra suction required, using carbon fiber filter technology to reduce chlorine taste and odor for better-tasting water.

Some sport bottles are engineered with an optimized shape and cage fit to securely fit a variety of standard bottle cages; check the product description for specific fit details.

The listed 24 oz bottles show heights ranging from about 10.47 in to 11.2 in and widths from about 2.91 in to 3.6 in.
