Core Flask

The ION Core Flask is your daily hydration companion—engineered for uptime. With a 17-ounce double-walled stainless steel build, this bottle locks in heat or chill like your code locks in logic. Coffee stays hot through your first sprint. Water stays cold through your last standup.

The leak-proof, odor-resistant cap means no spills, no funk—just clean, high-performance hydration whether you’re commuting, climbing, or coding deep in your zone.
