ROCKBROS 21oz Bicycle Water Bottle with 5hrs Insulation and Leakproof Design

"Healthy Concerns Addressed with Better Materials" When designing our bike water bottle, we prioritize food health concerns. The bottle spout is made of food grade silicone to ensure your health, and the body is made of PP5 material that can withstand high temperatures of 75°, preventing melting and the production of toxic substances.

"Effortless Hydration with Easy Squeeze Design" Thanks to the PP5 material, this bike water bottle can be easily squeezed, allowing you to intake more water with less effort while cycling. The large bottle spout makes it easy to hydrate quickly and stay hydrated during your exercise routine.

"Perfectly Sized for All Bottle Cages" With a diameter of 7.4cm/2.9 inches, this bike water bottle is designed to fit all sizes of bottle cages on the market. You can confidently choose your cycling gear without worrying about compatibility.

"Long Lasting Insulation with Laminated Foam" Insulation is crucial, especially in extreme temperatures. Our water bottle features polyethylene foam insulation that can keep water cold or warm for over 5 hours. In our experiments, the bottle was able to keep ice cubes from melting even in the summer heat.

"Convenient High Flow Design with Self-sealing Spout" In addition to the high flow design, our water bottle also features a self-sealing spout. Pull out the spout to unlock the seal, and press it to reseal the bottle without the need to close the lid. A dust plug is included for added convenience.
