The Rotera series was made for all day hydration. We set out on a mission to create the perfect water bottle, and we did just that. So, what makes it different? The TwistSip™ straw lid offers on-demand sanitary sips, our signature ColdKey™ stainless steel straw prevents plastic from sitting in your water all day, our BevGuard™ technology keeps ice for 24 hours and the swappable soft-touch sleeve makes this the most durable and customizable insulated bottle ever.
