The Under Armour hydration bottle line from Thermos was built with the active athlete in mind. Athletes need to perform their best, and that starts with proper hydration. The Under Armour ILLUSION 24-ounce squeeze bottle with quick shot lid is made with pliable and easy to squeeze BPA-free LDPE material and soft touch TPE grips that are comfortable to hold. The quick shot lid has a one-way valve for high water flow and locks closed with a twist.
