The double-wall vacuum-insulated walls give you a worry-free mind knowing your favorite beverages are kept icy cold or piping hot for hours.  Made of lightweight 18/8 food-grade stainless steel that is non-leaching and will not retain taste or odor. The double-wall technology prevents condensation on the outside for those hot sunny days while keeping the heat within the inner wall so you don't have to worry about burning your hand. 

The 25oz bottle is the optimal size to use as your everyday water bottle and designed to fit in your backpack and most car cup holders with its narrow bottle design. The vacuum-insulated walls ensure when you fill it with your ice-cold water in the morning it will last until your next refill. The double-wall technology prevents sweating on the outside of the bottle, so you don't have to worry about it slipping out of your hand on your afternoon run. 

The 25oz bottle includes a narrow mouth leak-proof sports cap lid. The silicone ring ensures a snug fit to the top of the bottle to retain your beverages' optimal temperature and is easily removable for proper cleaning. The lid is made to easily screw off and on your bottle. 

A great way to reduce your carbon footprint and keep you going no matter the adventure!

These are tough durable bottles, much more so than others costing more. The customer service was outstanding when I made a mistake on the order from not paying attention they made it right. Thank you Fifty/Fifty!

Review of bottle

The water inside stays cool for most of the day, I plan to put ice inside during winters to instantly cool off any drink I have. My only problem lies with the bottle cap. The sip part has lousy suction so it takes was more effort than should be necessary to actually drink it (hence anyone drinking from it looks like an idiotic child lol) I bought the larger one as a workaround but seriously as my only feedback fix your caps.

Awesome Bottle for A Great Price!

My other brand bottle finally stopped staying my beverages cold and started sweating, thus began my search for a new one. A coworker recommended this brand and so I jumped onto the website and found this bottle. It was the perfect size and the color even more amazing. I love the sea foam color and loved it even more I could pick the type of top I got which was awesome since I wanted a top I didn't have to unscrew every time I wanted to take a sip of water. Product came extremely fast (within 4 days of ordering).

Excellent ice retention

I use my 25 oz sport bottle at the gym each morning. I leave before everyone in the house is up, so I have to put ice in my fiftyfifty bottle before I go to bed the night before. When I fill with water the next day I find that minimal ice has melted. I always get ice cold water when I work out and that's important to my morale. The slimmer size of the bottle makes it easier for my small hands to grab it when I'm between exercises, but I find myself grabbing and picking it up by the two-finger lid most often. The only beef I have is with the suction of the lid. Sometimes it allows me to suck more than once before the suction has to be released, and sometimes it only lets me do it once. That doesn't affect anything with the bottle, and it didn't stop me from purchasing 6 of these in different colors. I seriously love my fiftyfifty bottles and buy them for gifts for others.
