Whether you're cheering from the sidelines at a marathon or coaching through a weekend tournament, the Yeti Silo Half Gallon Straw Jug delivers ice-cold hydration that keeps up with your most demanding athletic adventures. Built with the same PermaFrost™ insulation and virtually indestructible RockSolid™ materials as Yeti's legendary Roadie® Hard Coolers, this 1.8L sports hydration powerhouse maintains frigid temperatures through those grueling triple-overtime games and all-day track meets. The over-engineered ergonomic handle features built-in fence hooks that let you hang it courtside or poolside, while the 100% leakproof covered straw with MagSlider™ technology ensures mess-free sipping whether you're running drills or running miles. At just over 1 kg empty, it's the grab-and-go hydration solution that refuses to quit when the competition heats up.
