The Elite Fly is WorldTour’s most used water bottle because it’s incredibly lightweight. It’s the world’s lightest bottle.
Its record weight (at only 54g for the 550 ml version) makes it possible for us to use less plastic material as we make it, and guarantee the Elite-classic ergonomic structure that it's easy to squeeze so liquid flow is abundant with the lightest pressure.
Fly Elite is available in many different colour options for a perfect match with your bike and your bottle cage.
Extreme liquid flow
The ergonomic cap with wider flat push-pull nozzle and a wider mouth ensure high liquid flow, which is also guaranteed by the soft bottle body: you will just need to squeeze gently your Fly Elite to get a vigorous liquid flow.
Easy to open and close with your mouth, the Fly’s valve is ideal when you’re using this bottle while you’re moving on your bike. The bigger opening make it easy to fill the bottle up and wash it properly.
Compact design
Feturing a new racing design, the Elite Fly bottles work extraordinary well and stable in all cages so that bottle insertion and extraction are smooth and easy every time you're riding. Compact design means the Fly is perfect for road bikes as well as gravel bikes and mountain bikes that feature smaller frames.
The bottle’s practical and sustainable structure is designed to eliminate excess material during production and, by doing so, have the lightest product in the market with no waste.
Less plastic, only performance
Elite firmly believes that each athlete is responsible for taking care of the world and the environment everyone rides in. In developing our products and implementing new sustainable manufacturing processes, we consider both materials and technologies. That’s why we’re proud to use over 30% less plastic than average to create one single bottle of the Fly range.
By making our Fly bottles so lightweight by design, we can significantly reduce our carbon footprint and help ease pressure on the environment by ensuring the lowest CO2 emissions from our produtcion of water bottles.
Hygienic, innovative materials
This bottle is manufactured using innovative, odorless, soft and resistant plastic materials, which is the result of a 3-year long study conducted with multiple universities research centers.
The Fly Elite is also hygienic and easy to wash. It features a 20% wider mouth compared to standard bottles to help our customers achieve better hydration and properly hygienize their bottles. Fly bottles are also dishwasher safe at 40°C and make it easy to disassemble, so you can dry both the bottle body and the cap with nozzle and avoid any mold growth inside or the subsequent bad smell.
