ROCKBROS 21oz Bicycle Water Bottle for Sports

We take all food health issues seriously and carefully consider them when designing our bike water bottles. To ensure your health, this water bottle adopts food-grade silicone on the bottle spout. Additionally, the PP5 material of the body can withstand high temperatures of up to 75°C, preventing melting and the production of toxic substances. [Better Materials for Healthy Concern]

The PP5 material also gifts this bike water bottle the advantage of easy squeezing, allowing you to intake more water with less effort to support your cycling. Cooperating with the large bottle spout, this design enables quick hydration, keeping you online during exercise or cycling at all times. [Easy Squeeze to Intake More Fluid]

Designed with an optimized body size, this bike water bottle has a diameter of 7.4cm/2.9 inches, allowing it to fit almost all standard bottle cages on the market. We hope you can feel free to choose your cycling gear without concern about its size. [Optimized Size to Fit all Cages]

Insulation is important to everyone, especially in hot summer or cold winter. This water bottle adopts polyethylene foam in the interlayer to keep water cold or warm when you need it. After our experiment, this bottle can keep ice cubes from melting for over 5 hours in the summer. [Laminated Foam for Insulating over 5hrs]

In addition to the high-flow benefit from its large spout, this water bottle also adopts a self-sealing design. Pulling out the spout unlocks the sealing, and pressing the spout achieves self-sealing. This design helps lock the water easily without closing the lid. A dust plug is also included with the bottle for your convenience. [High Flow & Self-sealing Bottle Spout]

By incorporating these features, we aim to provide you with a bike water bottle that not only ensures your health and hydration but also offers convenient and versatile functionality. Whether you're an avid cyclist, an outdoor enthusiast, or simply someone who values a reliable and well-designed water bottle, this product is a perfect choice to accompany you on your adventures.
