A bike bottle that doesn’t leak! The On the Fly Bottle by our friends at Nalgene is a great hard sided bottle with a easy-to-open top. As the name so aptly describes, you can open the top while “on the fly” with just one hand. It fits perfectly in most bike bottle cages. Made out of an impact resistant material, we can attest to its durability, because we accidentally dropped it, and it survived without a crack! Don’t limit yourself to only using when you go biking though, take it on that hike with you and feel confident that it won’t leak in your backpack. It’s also dishwasher safe, so it’s super convenient to keep clean!
