evo.com | Bivo Water Bottles > Smaller and lighter than it's vacuum insulated siblings, the Bivo One 21oz Water Bottle is the first stainless-steel bottle designed to deliver the flow-rate cyclists want. Designed in collaboration with an ex-NASA engineer, this water bottle delivers the clean taste we all love about stainless steel but with a universal bike cage fit and anti-slip silicone exterior so it's not rattling about as you ride down bumpy trails. Patented High-Flow Sport Nozzle Better flow by design. Leveraging the experience of their ex-NASA engineer, Bivo methodically developed the Trio to achieve an unmatched flow-rate without the need to squeeze. The result is a smooth, consistent and enjoyable drinking experience we know you'll love. Single-Wall Non-Insulated Bivo knew some of you would be skeptical of having heavier bottles, so they launched with the single-wall version. Some benefits of the single-wall construction are that they are smaller and lighter than their insulated sibling. Silicone Anti-Slip Exterior Less rattle. More roll. Whether it is a long grind through a washboarded gravel road or the next hit on your mountain bike, Bivo designed the Trio's silicone exterior coating to keep your bottle in your hand, in your cage, and quiet enough to hear the birds. 100% Recyclable Stainless Steel Lid is interchangeable with the Bivo Duo. | Bivo One 21oz Water Bottle 2024 - 21oz in Silver
