When your training demands everything you've got, your hydration gear needs to match that intensity. The Yeti Silo 40 oz Straw Jug is engineered specifically for athletes who refuse to compromise, delivering ice-cold refreshment that powers through the most grueling workouts, practices, and training sessions. Built with the same PermaFrost™ insulation technology found in Yeti's legendary hard coolers, this athletic water bottle maintains drink temperature through intense reps, sprints, and scrimmages while the 100% leakproof straw cap lets you hydrate quickly without breaking stride. The ingeniously designed fence hooks built into the ergonomic handle transform any dugout, gym rack, or field fence into your personal hydration station, while RockSolid™ strength construction laughs off the drops and dings that come with serious athletic training.
