Splashguard | Blue

Stop spills in their tracks with this innovative silicone cap from Guyot Designs. The smart two-opening system gives you a small sipping port that prevents splashes during movement, and a larger fill opening so you can refill on the fly without taking the cap off. Crafted from food-grade silicone that resists odors and flavors, it's boilable for sterilization and dishwasher safe for easy cleanup. The flexible construction adapts to fit wide-mouth bottles from all the major brands—Nalgene®, Cyclone™, Bison™, GSI™, and beyond—and the opening size works equally well for kids and adults. Whether you're hiking, paddling, or commuting, this trusted original keeps your hydration secure and your gear dry.
