The large nozzle opening gives you ample water flow, while the wide-mouth bottle opening lets you fill it quickly and add ice without a hassle. Both of these features make for fast, easy cleaning by hand, though the bottle can be placed safely in the top rack of your dishwasher, too. The Podium Chill's lockout dial with easy-to-read graphics enables leak-proof transport. Additionally, the bottle features a streamlined ergonomic design that makes it easy to squeeze without compromising your grip. Its TruTaste polypropylene plastic is a proprietary blend that is food-safe and taste-free, so as not to flavor or otherwise alter the taste of your water. The Chill also incorporates HydroGuard, a proprietary antimicrobial technology embedded directly into the bottle walls. HydroGuard is an EPA-registered compound designed to inhibit the growth of bacteria that can cause odors, discoloration, and deterioration.
