Staying hydrated is critical to having a good day on the bike, mainly if you’re working hard or riding in the heat of summer. But when you’re focused on the road ahead, a no-brainer plan like “drink when you’re thirsty” can entirely fall apart with even the tiniest barrier to fluid intakes—like a leaky bottle valve, a hard-to-open mouthpiece, or an awful plastic taste to your water. The best water bottles solve those problems and make staying hydrated a little easier, so you don’t have to think about it.
